CSA231NATSSOP8 from analogysemi, in a TSSOP-8. 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 NC unconnected No connect; the datasheet says do not connect.
2 RS+ input External sense resistor power-side connection; input common-mode range 0V to 76V (abs max 80V).
3 RS- input External sense resistor load-side connection; input common-mode range 0V to 76V (abs max 80V).
4 GND power_in Ground.
5 VDD power_in Supply voltage of 2.7V to 5.5V, bypassed with at least a 100nF capacitor to GND.
6 REF2 input Reference voltage input 2, typically connected to GND.
7 REF1 input Reference voltage input 1, typically connected to VDD.
8 OUT output Output voltage, referenced to 1/2 (REF1 + REF2).
