INA219BIDCNT

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

INA219BIDCNT 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 Positive differential shunt voltage input, differential voltage range -26 to +26 V maximum.
2 IN- input Negative differential shunt voltage input, common-mode voltage range -0.3 to 26 V maximum.
3 GND power_in Analog ground reference connection.
4 VS power_in Analog power supply voltage, operating range 3 to 5.5 V, absolute maximum 6 V.
5 SCL input Serial bus clock line for I²C/SMBus interface, voltage range GND-0.3 to VS+0.3 V maximum.
6 SDA bidirectional Serial bus data line for I²C/SMBus interface (open-drain output), voltage range GND-0.3 to 6 V maximum.
7 A0 input Address selection input pin for I²C slave address configuration, state sampled on every bus communication.
8 A1 input Address selection input pin for I²C slave address configuration, state sampled on every bus communication.
