**Texas Instruments** · Differential Amplifiers · SOIC-8

INA597IDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF | input | Reference input connected via 6-kΩ resistor to op-amp noninverting terminal; used as reference pin in G = ½ configuration and positive input in G = 2 configuration. |
| 2 | −IN | input | Inverting input connected via 12-kΩ resistor to op-amp inverting terminal; used as negative input in G = ½ configuration and feedback connection in G = 2 configuration. |
| 3 | +IN | input | Noninverting input connected via 12-kΩ resistor to op-amp noninverting terminal; used as positive input in G = ½ configuration and reference pin in G = 2 configuration. |
| 4 | V− | power_in | Negative (lowest) power supply rail; single-supply 4.5 V to 36 V or dual-supply ±2.25 V to ±18 V. |
| 5 | SENSE | input | Feedback input connected via 6-kΩ resistor to op-amp inverting terminal; connected to output in G = ½ configuration and used as negative input in G = 2 configuration. |
| 6 | OUT | output | Amplifier output. |
| 7 | V+ | power_in | Positive (highest) power supply rail; single-supply 4.5 V to 36 V or dual-supply ±2.25 V to ±18 V. |
| 8 | NC | unconnected | No internal connection; pin can be left floating. |
