INA333AIDGKT

Texas Instruments · Instrumentation Amplifiers · VSSOP-8

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.
