INA293B4QDBVRQ1

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

INA293B4QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 OUT output Output voltage of the current sense amplifier, limited to GND - 0.3 V to Vs + 0.3 V per the absolute maximum ratings.
2 GND power_in Ground reference pin for the device.
3 Vs power_in Power supply input, specified for 2.7 V to 20 V operation with an absolute maximum range of -0.3 V to 22 V.
4 IN+ input Shunt resistor positive sense input, with a common-mode range of -4 V to 110 V in operation and -20 V to 120 V survival.
5 IN- input Shunt resistor negative sense input, with a differential voltage limit of ±12 V for this variant (INA293B4 is not one of the ±6 V A5/B5 variants).
