INA823DGKR from Texas Instruments, in a MSOP-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 | RG | passive | Gain-setting pin. Place an external gain resistor R_G between pin 1 and pin 8; gain is set by G = 1 + 100 kΩ / R_G (range G = 1 to 10,000). |
| 2 | -IN | input | Negative (inverting) instrumentation amplifier input. Input overvoltage protection to ±60 V; usable input range extends 150 mV below the negative supply. |
| 3 | +IN | input | Positive (noninverting) instrumentation amplifier input. Input overvoltage protection to ±60 V; usable input range extends 150 mV below the negative supply. |
| 4 | -VS | power_in | Negative supply rail. Single-supply operation uses -VS = GND with +VS = 2.7 V to 36 V; dual-supply operation uses ±1.35 V to ±18 V. |
| 5 | REF | input | Reference input that sets the output common-mode voltage. Must be driven by a low-impedance source; input impedance is 100 kΩ and reference gain to output is 1 V/V. |
| 6 | OUT | output | Amplifier output. Output swings to within 0.15 V of each supply rail; short-circuit current is continuous to V_S / 2 (typ ±20 mA). |
| 7 | +VS | power_in | Positive supply rail. Single-supply 2.7 V to 36 V, or dual-supply ±1.35 V to ±18 V. Quiescent current is 180 µA (typ). |
| 8 | RG | passive | Gain-setting pin. Place an external gain resistor R_G between pin 1 and pin 8; gain is set by G = 1 + 100 kΩ / R_G. |
