INA819IDGKR 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 a gain resistor between pin 2 and pin 3, with G = 1 + 50 kΩ / RG. |
| 3 | RG | passive | Gain setting pin; place a gain resistor between pin 2 and pin 3, with G = 1 + 50 kΩ / RG. |
| 4 | +IN | input | Positive (noninverting) input; signal input pins are rated -60 V to 60 V absolute maximum. |
| 5 | -VS | power_in | Negative supply; recommended operation is ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply. |
| 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; maximum voltage is (-Vs) - 0.5 V to (+Vs) + 0.5 V and maximum output current is ±50 mA. |
| 8 | +VS | power_in | Positive supply; recommended operation is 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply, with absolute maximum of 40 V single or ±20 V dual. |
