CSA231NASOIC8

analogysemi · Current Sense Amplifiers · SOIC-8

CSA231NASOIC8 from analogysemi, in a SOIC-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 RS- input External resistor load-side connection; the sense input for the load side of RSENSE, with VRS+ and VRS- limited to 0 V to 76 V to GND and VRS+ - VRS- limited to ±1 V.
2 GND power_in Power ground, the device ground reference; the VDD supply is specified from 2.7 V to 5.5 V relative to GND.
3 REF2 input Reference voltage input 2, typically connected to GND; the VREF input range is GND to VDD.
4 NC unconnected Do not connect.
5 OUT output Output, which equals 1/2 (REF1 + REF2) at zero sense voltage; the output is high-Z during power-up.
6 VDD power_in Supply voltage, with at least a 100nF capacitor connected to GND; the supply range is 2.7 V to 5.5 V.
7 REF1 input Reference voltage input 1, typically connected to VDD; the VREF input range is GND to VDD.
8 RS+ input External resistor power-side connection; the sense input for the supply side of RSENSE, with VRS+ and VRS- limited to 0 V to 76 V to GND.
