Texas Instruments · Current Sense Amplifiers · TSSOP-16

INA250A1PWR from Texas Instruments, in a TSSOP-16. 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 connected to load.
2 IN- input Analog input connected to load.
3 IN- input Analog input connected to load.
4 SH- output Analog output, Kelvin connection to internal shunt; connect to VIN- if no filtering is needed.
5 VIN- power_in Analog input, voltage input from load side of shunt resistor.
6 GND power_in Analog ground.
7 REF input Analog input, reference voltage 0 V to VS (up to 18 V).
8 GND power_in Analog ground.
9 OUT output Analog output, output voltage.
10 VS power_in Analog power supply, 2.7 V to 36 V.
11 GND power_in Analog ground.
12 VIN+ power_in Analog input, voltage input from supply side of shunt resistor.
13 SH+ output Analog output, Kelvin connection to internal shunt; connect to VIN+ if no filtering is needed.
14 IN+ input Analog input connected to supply.
15 IN+ input Analog input connected to supply.
16 IN+ input Analog input connected to supply.
