Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Channel A amplifier output, delivers 15 mA with dropout below 1.2 V and drives up to 1000 pF without external compensation. |
| 2 | -INA | input | Channel A inverting input with internal 500 Ω series resistor, tolerates up to 2.5 V beyond the supply rails without output phase inversion. |
| 3 | +INA | input | Channel A non-inverting input with internal 500 Ω series resistor, tolerates up to 2.5 V beyond the supply rails without output phase inversion. |
| 4 | V- | power_in | Negative supply pin; total supply (V+ to V-) is 5 V to 25 V (±2.5 V to ±12.5 V dual supply). |
| 5 | +INB | input | Channel B non-inverting input with internal 500 Ω series resistor, tolerates up to 2.5 V beyond the supply rails without output phase inversion. |
| 6 | -INB | input | Channel B inverting input with internal 500 Ω series resistor, tolerates up to 2.5 V beyond the supply rails without output phase inversion. |
| 7 | OUTB | output | Channel B amplifier output, delivers 15 mA with dropout below 1.2 V and drives up to 1000 pF without external compensation. |
| 8 | V+ | power_in | Positive supply pin; absolute maximum supply voltage (V+ to V-) is 25 V, with about 680 µA typical supply current per amplifier. |
