EL5220C, EL5420C
12MHz Rail-to-Rail Input-Output Op Amps
Features
* 12MHz -3dB bandwidth * Supply voltage = 4.5V to 16.5V * Low supply current (per amplifier) = 500A * High slew rate = 10V/s * Unity-gain stable * Beyond the rails input capability * Rail-to-rail output swing * Ultra-small package
General Description
The EL5420C and EL5220C are low power, high voltage, rail-to-rail input-output amplifiers. The EL5220C contains two amplifiers in one package, and the EL5420C contains four amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 500A per amplifier, the EL5420C and EL5220C have a bandwidth of 12MHz -(-3dB). They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables these amplifiers to offer maximum dynamic range at any supply voltage. The EL5420C and EL5220C also feature fast slewing and settling times, as well as a high output drive capability of 30mA (sink and source). These features make these amplifiers ideal for use as voltage reference buffers in Thin Film Transistor Liquid Crystal Displays (TFT-LCD). Other applications include battery power, portable devices, and anywhere low power consumption is important. The EL5420C is available in a space-saving 14-pin TSSOP package, the industry-standard 14-pin SO package, as well as a 16-pin LPP package. The EL5220C is available in the 8-pin MSOP package. Both feature a standard operational amplifier pin out. These amplifiers are specified for operation over the full -40C to +85C temperature range.

Applications Information
Product Description
The EL5220C and EL5420C voltage feedback amplifiers are fabricated using a high voltage CMOS process. They exhibit rail-to-rail input and output capability, they are unity gain stable, and have low power consumption (500A per amplifier). These features make the EL5220C and EL5420C ideal for a wide range of general-purpose applications. Connected in voltage follower mode and driving a load of 10k and 12pF, the EL5220C and EL5420C have a -3dB bandwidth of 12MHz while maintaining a 10V/s slew rate. The EL5220C is a dual amplifier while the EL5420C is a quad amplifier.
VS=5V TA=25C AV=1 VIN=10VP-P
Figure 1. Operation with Rail-to-Rail Input and Output Short Circuit Current Limit
The EL5220C and EL5420C will limit the short circuit current to 120mA if the output is directly shorted to the positive or the negative supply. If an output is shorted indefinitely, the power dissipation could easily increase such that the device may be damaged. Maximum reliability is maintained if the output continuous current never exceeds 30 mA. This limit is set by the design of the internal metal interconnects.
Operating Voltage, Input, and Output
The EL5220C and EL5420C are specified with a single nominal supply voltage from 5V to 15V or a split supply with its total range from 5V to 15V. Correct operation is guaranteed for a supply range of 4.5V to 16.5V. Most EL5220C and EL5420C specifications are stable over both the full supply range and operating temperatures of -40 C to +85 C. Parameter variations with operating voltage and/or temperature are shown in the typical performance curves. The input common-mode voltage range of the EL5220C and EL5420C extends 500mV beyond the supply rails. The output swings of the EL5220C and EL5420C typically extend to within 80mV of positive and negative supply rails with load currents of 5mA. Decreasing load currents will extend the output voltage range even closer to the supply rails. Figure 1 shows the input and output waveforms for the device in the unity-gain configuration. Operation is from 5V supply with a 10k load connected to GND. The input is a 10VP-P sinusoid. The output voltage is approximately 9.985VP-P.
Output Phase Reversal
The EL5220C and EL5420C are immune to phase reversal as long as the input voltage is limited from (VS-) ----0.5V to (VS+) +0.5V. Figure 2 shows a photo of the output of the device with the input voltage driven beyond the supply rails. Although the device's output will not change phase, the input's overvoltage should be avoided. If an input voltage exceeds supply voltage by more than 0.6V, electrostatic protection diodes placed in the input stage of the device begin to conduct and overvoltage damage could occur.

Figures 3, 4, and 5 provide a convenient way to see if the device will overheat. The maximum safe power dissipation can be found graphically, based on the package type and the ambient temperature. By using the previous equation, it is a simple matter to see if PDMAX exceeds the device's power derating curves. To ensure proper operation, it is important to observe the recommended derating curves in Figures 3, 4, and 5.

Figure 2. Operation with Beyond-the-Rails Input Power Dissipation
With the high-output drive capability of the EL5220C and EL5420C amplifiers, it is possible to exceed the 125C "absolute-maximum junction temperature" under certain load current conditions. Therefore, it is important to calculate the maximum junction temperature for the application to determine if load conditions need to be modified for the amplifier to remain in the safe operating area. The maximum power dissipation allowed in a package is determined according to:

1200 1000 Power Dissipation (mW)
where: TJMAX = Maximum Junction Temperature TAMAX= Maximum Ambient Temperature JA = Thermal Resistance of the Package PDMAX = Maximum Power Dissipation in the Package The maximum power dissipation actually produced by an IC is the total quiescent supply current times the total power supply voltage, plus the power in the IC due to the loads, or:

the peaking increase. The amplifiers drive 10pF loads in parallel with 10k with just 1.5dB of peaking, and 100pF with 6.4dB of peaking. If less peaking is desired in these applications, a small series resistor (usually between 5 and 50) can be placed in series with the output. However, this will obviously reduce the gain slightly. Another method of reducing peaking is to add a "snubber" circuit at the output. A snubber is a shunt load consisting of a resistor in series with a capacitor. Values of 150 and 10nF are typical. The advantage of a snubber is that it does not draw any DC load current or reduce the gain

Power Supply Bypassing and Printed Circuit Board Layout
The EL5220C and EL5420C can provide gain at high frequency. As with any high-frequency device, good printed circuit board layout is necessary for optimum performance. Ground plane construction is highly recommended, lead lengths should be as short as possible and the power supply pins must be well bypassed to reduce the risk of oscillation. For normal single supply operation, where the VS- pin is connected to ground, a 0.1F ceramic capacitor should be placed from VS+ to pin to VS- pin. A 4.7F tantalum capacitor should then be connected in parallel, placed in the region of the amplifier. One 4.7F capacitor may be used for multiple devices. This same capacitor combination should be placed at each supply pin to ground if split supplies are to be used.

It is recommended that any unused amplifiers in a dual and a quad package be configured as a unity gain follower. The inverting input should be directly connected to the output and the non-inverting input tied to the ground plane.
Driving Capacitive Loads
The EL5220C and EL5420C can drive a wide range of capacitive loads. As load capacitance increases, however, the -3dB bandwidth of the device will decrease and
