INA241A1IDDFR

Texas Instruments · Current Sense Amplifiers · SOT-23-8

INA241A1IDDFR from Texas Instruments, in a SOT-23-8. 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 Current sense amplifier negative input for differential voltage measurement; common-mode input voltage range -5V to +110V.
2 GND power_in Device ground reference and return path for all circuits.
3 REF2 input Reference 2 voltage input; accepts 0V to VS for setting output voltage baseline per gain equation.
4 NC unconnected Reserved no-connect pin; must be connected to ground per datasheet.
5 OUT output Analog output voltage with swing from GND+20mV to VS-200mV representing amplified differential current sense signal.
6 VS power_in Positive power supply input; accepts 2.7V to 20V for device bias and output stage operation.
7 REF1 input Reference 1 voltage input; accepts 0V to VS for setting output voltage baseline per gain equation.
8 IN+ input Current sense amplifier positive input for differential voltage measurement; common-mode input voltage range -5V to +110V.
