CSA240LQCSOIC8

analogysemi · Current-Sensing Amplifiers · SOIC-8

CSA240LQCSOIC8 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 IN− input Analog input; connect to the load side of the shunt resistor, with a common-mode input range of −6 V to 80 V (Table 5).
2 GND power_in Analog ground reference for the device.
3 REF2 input Reference 2 voltage input; connect to 0 V to VS and do not drive it below GND or above VS.
4 NC unconnected Reserved; connect to ground or leave floating.
5 OUT output Analog output voltage; the output is limited to GND − 0.3 V to VS + 0.3 V (Table 3).
6 VS power_in Power supply input, 2.7 V to 5.5 V.
7 REF1 input Reference 1 voltage input; connect to 0 V to VS and do not drive it below GND or above VS.
8 IN+ input Analog input; connect to the supply side of the shunt resistor, with a common-mode input range of −6 V to 80 V (Table 5).
