INA819IDR from Texas Instruments, in a SOIC-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 protected up to ±60 V. |
| 2 | RG | passive | Gain setting pin; place a gain resistor between pin 2 and pin 3. |
| 3 | RG | passive | Gain setting pin; place a gain resistor between pin 2 and pin 3. |
| 4 | +IN | input | Positive (noninverting) input protected up to ±60 V. |
| 5 | -VS | power_in | Negative power supply rated 4.5-36 V single-supply or ±2.25-±18 V dual-supply. |
| 6 | REF | input | Reference input rated -20 to +20 V; must be driven by low impedance source. |
| 7 | OUT | output | Output rated (-Vs) - 0.5 to (+Vs) + 0.5 V, maximum ±50 mA. |
| 8 | +VS | power_in | Positive power supply rated 4.5-36 V single-supply or ±2.25-±18 V dual-supply. |
