# INA819IDGKT

**Texas Instruments** · Instrumentation Amplifiers · MSOP-8

INA819IDGKT from Texas Instruments, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -IN | input | Negative (inverting) input; signal input pins are rated -60 V to 60 V (absolute maximum). |
| 2 | RG | passive | Gain setting pin; place the gain resistor between pin 2 and pin 3. |
| 3 | RG | passive | Gain setting pin; place the gain resistor between pin 2 and pin 3. |
| 4 | +IN | input | Positive (noninverting) input; signal input pins are rated -60 V to 60 V (absolute maximum). |
| 5 | -VS | power_in | Negative supply; supply is 4.5 V to 36 V single-supply or ±2.25 V to ±18 V dual-supply (recommended operating conditions). |
| 6 | REF | input | Reference input that must be driven by a low impedance source; VREF pin is rated -20 V to 20 V (absolute maximum). |
| 7 | OUT | output | Output; signal output pins are limited to ±50 mA and to (-VS) - 0.5 V through (+VS) + 0.5 V (absolute maximum). |
| 8 | +VS | power_in | Positive supply; supply is 4.5 V to 36 V single-supply or ±2.25 V to ±18 V dual-supply (recommended operating conditions). |
