| 2 | VS- | power_in | Negative supply pin (one of pins 1-4), tied to ground in single-supply use; dual supply ±1.5 V to ±2.5 V, single supply 3 V to 5 V. |
| 3 | VS- | power_in | Negative supply pin (one of pins 1-4), tied to ground in single-supply use; dual supply ±1.5 V to ±2.5 V, single supply 3 V to 5 V. |
| 4 | VS- | power_in | Negative supply pin (one of pins 1-4), tied to ground in single-supply use; dual supply ±1.5 V to ±2.5 V, single supply 3 V to 5 V. |
| 5 | VOUT | output | Amplifier output (one of pins 5-8) with fixed gain of +5 V/V and ±180 mA output drive; place any isolation resistor close to this pin when driving capacitive loads. |
| 6 | VOUT | output | Amplifier output (one of pins 5-8) with fixed gain of +5 V/V and ±180 mA output drive; place any isolation resistor close to this pin when driving capacitive loads. |
| 7 | VOUT | output | Amplifier output (one of pins 5-8) with fixed gain of +5 V/V and ±180 mA output drive; place any isolation resistor close to this pin when driving capacitive loads. |
| 8 | VOUT | output | Amplifier output (one of pins 5-8) with fixed gain of +5 V/V and ±180 mA output drive; place any isolation resistor close to this pin when driving capacitive loads. |
| 9 | VS+ | power_in | Positive supply pin (one of pins 9-12), 3 V to 5 V single supply with absolute maximum supply voltage of 6 V; decouple closely. |
| 10 | VS+ | power_in | Positive supply pin (one of pins 9-12), 3 V to 5 V single supply with absolute maximum supply voltage of 6 V; decouple closely. |
| 11 | VS+ | power_in | Positive supply pin (one of pins 9-12), 3 V to 5 V single supply with absolute maximum supply voltage of 6 V; decouple closely. |
| 12 | VS+ | power_in | Positive supply pin (one of pins 9-12), 3 V to 5 V single supply with absolute maximum supply voltage of 6 V; decouple closely. |
| 13 | NC | unconnected | No connect. |
| 14 | VIN- | power_in | Inverting input node, which is the return of the internal 50 Ω Rg gain resistor and should be connected to ground through a very low inductance path (minimum of 5 vias recommended). |
| 15 | VIN+ | power_in | Noninverting input with 1.6 MΩ input resistance and common-mode input range of VS- +1 V to VS+ -1 V. |
| 16 | PD | input | Power-down control that defaults to the positive supply (power on) when left unconnected; above 1.5 V the device is on and below 0.9 V it is off, reducing quiescent current from 37 mA to about 0.8 mA. |
| 17 | EP | passive | Exposed PowerPAD thermal pad, electrically isolated from all other pins, which must be soldered to a thermally dissipative copper plane. |
