INA333AIDGKT from Texas Instruments, in a VSSOP-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 resistor terminal; connect external resistor between pins 1 and 8 to set gain according to G = 1 + (100kΩ/RG) for gain range 1 to 1000 V/V. |
| 2 | VIN- | power_in | Negative (inverting) differential input; common-mode input voltage range from (V-) + 0.1V to (V+) - 0.1V; differential input impedance 100 GΩ |
| 3 | VIN+ | power_in | Positive (non-inverting) differential input; common-mode input voltage range from (V-) + 0.1V to (V+) - 0.1V; differential input impedance 100 GΩ |
| 4 | V- | power_in | Negative power supply terminal; supply voltage range 1.8V to 5.5V in single-supply mode or ±0.9V to ±2.75V in dual-supply mode; absolute maximum 7V. |
| 5 | REF | input | Reference input for output DC level adjustment; must be driven by low impedance source or grounded; input impedance 300kΩ minimum. |
| 6 | VOUT | output | Analog output with rail-to-rail output capability; output voltage swing from (V-) + 50mV to (V+) - 50mV at RL = 10kΩ; supports capacitive load up to 500pF. |
| 7 | V+ | power_in | Positive power supply terminal; supply voltage range 1.8V to 5.5V in single-supply mode or ±0.9V to ±2.75V in dual-supply mode; absolute maximum 7V. |
| 8 | RG | passive | Gain setting resistor terminal; connect external resistor between pins 1 and 8 to set gain according to G = 1 + (100kΩ/RG) for gain range 1 to 1000 V/V. |
