General Description
This family of dual, triple, and quad operational amplifiers built using Elantec's Complementary Bipolar process offers unprecedented high frequency performance at a very low cost. They are suitable for any application such as consumer video, where traditional DC performance specifications are of secondary importance to the high frequency specifications. On 5V supplies at a gain of +1 the EL2210C, EL2310C, and EL2410C will drive a 150 load to +2V,---1V with a bandwidth of 50MHz and a channel-to-channel isolation of 60dB or more. At a gain of +2, the EL2211C, EL2311C, and EL2411C will drive a 150 load to +2V, -1V with a bandwidth of 100MHz with the same channel-to-channel isolation. All four achieve 0.1dB bandwidth at 5MHz. The power supply operating range is fixed at 5V or +10/0V. In single supply operation the inputs and outputs will operate to ground. Each amplifier draws only 7mA of supply current.

Application Information
Product Description
The EL2210C, EL2310C, and EL2410C are dual, triple, and quad operational amplifiers stable at a gain of 1. The EL2211C, EL2311C, and EL2411C are dual, triple, and quad operational amplifiers stable at a gain of 2. All six are built on Elantec's proprietary complimentary process and share the same voltage mode feedback topology. This topology allows them to be used in a variety of applications where current mode feedback amplifiers are not appropriate because of restrictions placed on the feedback elements. These products are especially designed for applications where high bandwidth and good video performance characteristics are desired but the higher cost of more flexible and sophisticated products are prohibitive. The negative swing can be increased by adding an external resistor of appropriate value from the output to the negative supply. The simplified block diagram shows an 820 external pull-down resistor. This resistor is in parallel with the internal 1250 resistor. This will increase the negative swing to
1250 x 820 V EE = 150 / -------------------------- + 150 1250 + 820
Or -1.16V
Power Dissipation and Loading
Without any load and a 10V supply difference the power dissipation is 70mW per amplifier. At 12V supply difference this increases to 105mW per amplifier. At 12V this translates to a junction temperature rise above ambient of 33C for the dual and 40C for the quad amplifier. When the amplifiers provide load current the power dissipation can rapidly rise. In 5V operation each output can drive a grounded 150 load to more than 2V. This operating condition will not exceed the maximum junction temperature limit as long as the ambient temperature is below 85C, the device is soldered in place, and the extra pull-down resistor is 820 or more. If the load is connected to the most negative voltage (ground in single supply operation) you can easily exceed the absolute maximum die temperature. For example the maximum die temperature should be 150C. At a maximum expected ambient temperature of 85C, the total allowable power dissipation for the SO8 package would be:
150 - 85P D = ----------------------- = 361mW 160C/W
Power Supplies
These amplifiers are designed to work at a supply voltage difference of 10V to 12V. These amplifiers will work on any combination of supplies. All electrical characteristics are measured with 5V supplies. Below 9V total supply voltage the amplifiers' performance will degrade dramatically. The quiescent current is a direct function of total supply voltage. With a total supply voltage of 12V the quiescent supply current will increase from a typical 6.8mA per amplifier to 10mA per amplifier.
Output Swing vs Load
Please refer to the simplified block diagram. These amplifiers provide an NPN pull-up transistor output and a passive 1250 pull-down resistor to the most negative supply. In an application where the load is connected to VS- the output voltage can swing to within 200mV of VS-. In split supply applications where the DC load is connected to ground the negative swing is limited by the voltage divider formed by the load, the internal 1250 resistor and any external pull-down resistor. If RL were 150 then it and the 1250 internal resistor limit the maximum negative swing to
150 V EE = -------------------------1250 + 150
Or--0.53V
7
At 12V total supply voltage each amplifier draws a maximum of 10mA and dissipates 12V * 10mA = 120mW or 240mW for the dual amplifier. Which leaves 121mW of increased power due to the load. If the load were 150 connected to the most negative voltage and the maximum voltage out were VS- +1V the load current would be 6.67mA. Then an extra 146mW ((12V - 1V) * 6.67mA * 2) would be dissipated in the EL2210C or
EL2210C/11C, EL2310C/11C, EL2410C/11C
EL2210C/11C, EL2310C/11C, EL2410C/11C
Low Cost, Dual, Triple and Quad Video Op Amps
EL2211C. The total dual amplifier power dissipation would be 146mW + 240mW = 386mW, more than the maximum 361mW allowed. If the total supply difference were reduced to 10V, the same calculations would yield 200mW quiescent power dissipation and 120mW due to loading. This results in a die temperature of 143C (85C + 58C). In the above example, if the supplies were split 6V and the 150 loads were connected to ground, the load induced power dissipation would drop to 66.7mW (6.67mA * (6 - 1) * 2) and the die temperature would be below the rated maximum.
Printed-Circuit Layout
The EL2210C/EL2211C/EL2310C/EL2311C/ EL2410C/EL2411C are well behaved, and easy to apply in most applications. However, a few simple techniques will help assure rapid, high quality results. As with any high-frequency device, good PCB layout is necessary for optimum performance. Ground-plane construction is highly recommended, as is good power supply bypassing. A 0.1F ceramic capacitor is recommended for bypassing both supplies. Lead lengths should be as short as possible, and bypass capacitors should be as close to the device pins as possible. For good AC performance, parasitic capacitances should be kept to a minimum at both inputs and at the output. Resistor values should be kept under 5k because of the RC time constants associated with the parasitic capacitance. Metal-film and carbon resistors are both acceptable, use of wire-wound resistors is not recommended because of their parasitic inductance. Similarly, capacitors should be low-inductance for best performance.
Video Performance
Following industry standard practices (see EL2044C applications section) these six devices exhibit good differential gain (dG) and good differential phase (dP) with 5V supplies and an external 820 resistor to the negative supply, in a gain of 2 configuration. Driving 75 back terminated cables to standard video levels (1.428V at the amplifier) the EL2210C, EL2310C, and EL2410C have dG of 0.1% and dP of 0.2. The EL2211C, EL2311C, and EL2411C have dG of 0.04% and dP of 0.15. Due to the negative swing limitations described above, inverted video at a gain of 2 is just not practical. If swings below ground are required then changing the extra 820 resistor to 500 will allow reasonable dG and dP to approximately -0.75mV. The EL2211C, EL2311C, and EL2411C will achieve approximately 0.1%/0.4 between 0V and -0.75V. Beyond -0.75V dG and dP get worse by orders of magnitude. Differential gain and differential phase are fairly constant for all loads above 150. Differential phase performance will improve by a factor of 3 if the supply voltage is increased to 6V.
Output Drive Capability
None of these devices have short circuit protection. Each output is capable of more than 100mA into a shorted output. Care must be used in the design to limit the output current with a series resistor.
