INA293A1IDBVT

Texas Instruments · Current Sense Amplifiers · SOT-23-5

INA293A1IDBVT from Texas Instruments, in a SOT-23-5. 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 OUT output Analog output voltage. VOUT = Gain × (VIN+ − VIN−) with Gain = 20 V/V for INA293A1. Output swings from ~5 mV above GND up to Vs − 70 mV (Vs − 150 mV max) with a 10 kΩ load. Can drive up to 500 pF without an isolation resistor.
2 GND power_in Device ground reference. All voltages (supply, output swing, common-mode range) are referenced to this pin.
3 IN+ input Positive (high-side) shunt-resistor sense input. Connect to the more-positive terminal of the current-sense resistor. Common-mode range: -4 V to +110 V (absolute max -20 V to +120 V). Typical input bias current 20 µA when VSENSE = 0 V.
4 IN- input Negative (low-side) shunt-resistor sense input. Connect to the more-negative terminal of the current-sense resistor. Same -4 V to +110 V common-mode range as IN+. Differential (VIN+ − VIN−) absolute max is ±12 V for INA293A1.
5 Vs power_in Positive supply pin. Operating range 2.7 V to 20 V (abs max 22 V). Quiescent current 1.5 mA typical, 2 mA max. Decouple to GND with a low-ESR ceramic capacitor placed close to the pin.
