ISL24020 Data Sheet October 2, 2008 FN6735.0 Low Cost, 60MHz Rail-to-Rail Input-Output Op-Amp The ISL24020 is a low power, high voltage rail-to-rail inputoutput amplifier. Operating on supplies ranging from 5V to 15V, while consuming only 2.5mA per amplifier, the ISL24020 has a bandwidth of 60MHz (-3dB). It also provides common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables the amplifier to offer maximum dynamic range at any supply voltage. The ISL24020 also features fast slewing and settling times, as well as a high output drive capability of 65mA (sink and source). These features make the ISL24020 ideal for high speed filtering and signal conditioning application. Other applications include battery power, portable devices, and anywhere low power consumption is important. The ISL24020 is available in 5 Ld TSOT package. It features a standard operational amplifier pinout and operats over a temperature range of -40C to +85C.

It exhibits rail-to-rail input and output capability, is unity gain stable and has low power consumption (2.5mA). These features make the ISL24020 ideal for a wide range of general-purpose applications. Connected in voltage follower mode and driving a load of 1k, the ISL24020 has a -3dB bandwidth of 60MHz while maintaining a 75V/s slew rate. Output Phase Reversal The ISL24020 is immune to phase reversal as long as the input voltage is limited from VS- -0.5V to VS+ +0.5V. Figure 27 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. VS = 2.5V, TA = +25C, AV = 1, VIN = 6VP-P 1V 10s Operating Voltage, Input, and Output The ISL24020 is 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 ISL24020 specifications are stable over both the full supply range and operating temperatures of -40C to +85C. Parameter variations with operating voltage and/or temperature are shown in the "Typical Performance Curves" on page 3. The input common-mode voltage range of the ISL24020 extends 500mV beyond the supply rails. The output swings of the ISL24020 typically extend to within 100mV 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 26 shows the input and output waveforms for the device in the unity-gain configuration. Operation is from 5V supply with a 1k load connected to GND. The input is a 10VP-P sinusoid. The output voltage is approximately 9.8VP-P. VS = 5V, TA = +25C, AV = 1, VIN = 10VP-P 5V 10s 1V FIGURE 27. OPERATION WITH BEYOND-THE-RAILS INPUT Power Dissipation With the high-output drive capability of the ISL24020 amplifier, 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: INPUT T JMAX - T AMAX P DMAX = ------------------------------------------- JA (EQ. 1) where: * TJMAX = Maximum junction temperature * TAMAX = Maximum ambient temperature * JA = Thermal resistance of the package 5V FIGURE 26. OPERATION WITH RAIL-TO-RAIL INPUT AND OUTPUT OUTPUT * 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: P DMAX = i [ V S x I SMAX + ( V S + - V OUT i ) x I LOAD i ] (EQ. 2) Short Circuit Current Limit The ISL24020 will limit the short circuit current to 180mA 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 65mA. This limit is set by the design of the internal metal interconnects. when sourcing, and: P DMAX = i [ V S x I SMAX + ( V OUT i - V S - ) x I LOAD i ] (EQ. 3) when sinking. 8 FN6735.0 October 2, 2008 ISL24020 Where: * i = 1 to 2 for dual and 1 to 4 for quad * VS = Total supply voltage * ISMAX = Maximum supply current per amplifier * VOUTi = Maximum output voltage of the application * ILOADi = Load current If we set the two PDMAX equations equal to each other, we can solve for RLOADi to avoid device overheat. Power Supply Bypassing and Printed Circuit Board Layout The ISL24020 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. Unused Amplifiers 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. 9 FN6735.0 October 2, 2008 ISL24020 TSOT Package Family e1 A N 6 4 MDP0049 D TSOT PACKAGE FAMILY MILLIMETERS SYMBOL A A1 TSOT5 1.00 0.05 0.87 0.38 0.127 2.90 2.80 1.60 0.95 1.90 0.40 0.60 0.20 5 TSOT6 1.00 0.05 0.87 0.38 0.127 2.90 2.80 1.60 0.95 1.90 0.40 0.60 0.20 6 TSOT8 1.00 0.05 0.87 0.29 0.127 2.90 2.80 1.60 0.65 1.95 0.40 0.60 0.13 8 TOLERANCE Max 0.05 0.03 0.07 +0.07/-0.007 Basic Basic Basic Basic Basic 0.10 Reference Reference Rev.
