Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT_A | output | Output of amplifier 1; swings to within 8 mV of either rail into 10 kΩ or 125 mV into 600 Ω; short-circuit current ±75 mA. |
| 2 | -IN_A | input | Inverting input of amplifier 1; common-mode voltage range VS- − 0.1 V to VS+ + 0.1 V; input bias current 1 pA typical. |
| 3 | +IN_A | input | Non-inverting input of amplifier 1; same voltage range as -IN (VS- − 0.1 V to VS+ + 0.1 V). |
| 4 | VS- | power_in | Negative power supply; VS+ to VS- must not exceed 10 V; connect to GND in single-supply operation. |
| 5 | +IN_B | input | Non-inverting input of amplifier 2; voltage range VS- − 0.1 V to VS+ + 0.1 V. |
| 6 | -IN_B | input | Inverting input of amplifier 2; voltage range VS- − 0.1 V to VS+ + 0.1 V. |
| 7 | OUT_B | output | Output of amplifier 2; swings to within 8 mV of either rail into 10 kΩ or 125 mV into 600 Ω; short-circuit current ±75 mA. |
| 8 | OUT_C | output | Output of amplifier 3; swings to within 8 mV of either rail into 10 kΩ or 125 mV into 600 Ω; short-circuit current ±75 mA. |
| 9 | -IN_C | input | Inverting input of amplifier 3; voltage range VS- − 0.1 V to VS+ + 0.1 V. |
| 10 | +IN_C | input | Non-inverting input of amplifier 3; voltage range VS- − 0.1 V to VS+ + 0.1 V. |
| 11 | VS+ | power_in | Positive power supply; 1.8 V to 5.5 V at 0 °C to 70 °C, 2.0 V to 5.5 V at −40 °C to +125 °C; quiescent current 750 µA per amplifier at 5 V. |
| 12 | +IN_D | input | Non-inverting input of amplifier 4; voltage range VS- − 0.1 V to VS+ + 0.1 V. |
| 13 | -IN_D | input | Inverting input of amplifier 4; voltage range VS- − 0.1 V to VS+ + 0.1 V. |
| 14 | OUT_D | output | Output of amplifier 4; swings to within 8 mV of either rail into 10 kΩ or 125 mV into 600 Ω; short-circuit current ±75 mA. |
