INA187A1IDBVR

Texas Instruments · IC · SOT-23-6

INA187A1IDBVR from Texas Instruments, in a SOT-23-6. 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 (20V/V gain for INA187A1), swinging from about 80mV to 100mV below VS and limited to GND - 0.3V to VS + 0.3V.
2 GND power_in Ground.
3 IN+ input Current-sense amplifier positive input; connect to bus-voltage side of the sense resistor for high-side use or load side for low-side use, with a common-mode range of -2V to 42V.
4 IN- input Current-sense amplifier negative input; connect to load side of the sense resistor for high-side use or ground side for low-side use, with a common-mode range of -2V to 42V.
5 REF input Reference voltage input that sets the output at zero differential input; connect to a potential from 0V to VS.
6 VS power_in Power supply, 2.7V to 12V operating range (absolute maximum 13.2V relative to GND).
