INA317IDGKR from Texas Instruments, in a VSSOP-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 | RG | passive | Gain-setting pin; for gains greater than 1, a gain resistor is placed between pins 1 and 8, with gain G = 1 + (100 kΩ / RG). |
| 2 | VIN- | power_in | Negative input of the instrumentation amplifier; the features list the input voltage range as (V-) + 0.1 V to (V+) - 0.1 V. |
| 3 | VIN+ | power_in | Positive input of the instrumentation amplifier; the features list the input voltage range as (V-) + 0.1 V to (V+) - 0.1 V. |
| 4 | V- | power_in | Negative supply rail; the total supply voltage VS is specified at 1.8 V to 5.5 V. |
| 5 | REF | input | Reference input that must be driven by a low-impedance source or connected to ground. |
| 6 | VOUT | output | Amplifier output; the features list the output voltage range as (V-) + 0.05 V to (V+) - 0.05 V. |
| 7 | V+ | power_in | Positive supply rail; the total supply voltage VS is specified at 1.8 V to 5.5 V. |
| 8 | RG | passive | Gain-setting pin; for gains greater than 1, a gain resistor is placed between pins 1 and 8, with gain G = 1 + (100 kΩ / RG). |
