INA180B1QDBVRQ1

Texas Instruments · Current-Sensing Amplifiers · SOT-23-5

INA180B1QDBVRQ1 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN+ input Current-sense amplifier non-inverting analog input. In high-side applications, connect to the bus-voltage side of the sense resistor; in low-side applications, connect to the ground side of the sense resistor. Common-mode range -0.2 V to +26 V.
2 GND power_in Device ground reference. Tie to the system analog ground.
3 IN- input Current-sense amplifier inverting analog input. In high-side applications, connect to the load side of the sense resistor; in low-side applications, connect to the ground side of the sense resistor. Common-mode range -0.2 V to +26 V.
4 OUT output Buffered analog output voltage = Gain x (V(IN+) - V(IN-)); gain is fixed at 20 V/V for the B1 option. Rail-to-rail output typically within (VS - 0.03) V of VS and (GND + 0.005) V of GND with 10 kOhm load; 2 V/us slew rate; drives up to 1 nF capacitive load.
5 VS power_in Positive analog supply, 2.7 V to 5.5 V (absolute maximum 6 V). Bypass with a 0.1 uF ceramic capacitor to GND close to the pin. Typical quiescent current 260 uA (max 300 uA over -40 degC to +125 degC).
