Texas Instruments · Current Sense Amplifiers · SOIC-8

INA271AIDR from Texas Instruments, 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 to load-side shunt resistor terminal; common-mode voltage range -16V to +80V
2 GND power_in Analog ground reference
3 PRE OUT output Analog output from first gain stage; output voltage range GND - 0.3V to (V+) + 0.3V
4 BUF IN input Analog input from filter output; voltage range GND - 0.3V to (V+) + 0.3V
5 OUT output Analog output voltage from gain stage; output voltage range GND - 0.3V to (V+) + 0.3V
6 V+ power_in Power supply input; operating voltage range +2.7V to +18V
7 NC unconnected No internal connection; connect to ground
8 IN+ input Analog input to supply-side shunt resistor terminal; common-mode voltage range -16V to +80V
