INA333AIDRGT

Texas Instruments · Instrumentation Amplifiers · WSON-8-EP(3x3)

INA333AIDRGT from Texas Instruments, in a WSON-8-EP(3x3). 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; connect external resistor between pins 1 and 8 to set gain G = 1 + 100kΩ/RG.
2 VIN- power_in Negative (inverting) input; recommended input voltage range (V-) + 0.1 to (V+) - 0.1 V.
3 VIN+ power_in Positive (non-inverting) input; recommended input voltage range (V-) + 0.1 to (V+) - 0.1 V.
4 V- power_in Negative supply; operating voltage range 1.8 to 5.5 V.
5 REF input Reference input; must be driven by low impedance or connected to ground.
6 VOUT output Output; output voltage range (V-) + 0.05 to (V+) - 0.05 V.
7 V+ power_in Positive supply; operating voltage range 1.8 to 5.5 V.
8 RG passive Gain setting pin; connect external resistor between pins 1 and 8 to set gain G = 1 + 100kΩ/RG.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
