The Texas Instruments INA185A3IDRLT is a single-channel current sense amplifier in a SOT-563 package, designed to measure current by amplifying the voltage drop across a shunt resistor. It delivers a rail-to-rail output, runs from a 2.7 V to 5.5 V supply, and draws 200 µA quiescent current.
The 25 µV input offset voltage sets the floor on measurable shunt drop. The 75 µA input bias current is drawn from the shunt itself.
The INA185A3IDRLT has a fixed gain of 150 kHz gain-bandwidth product; the gain is set internally by the device variant (A3 suffix indicates a specific gain option, typically 100 V/V). Refer to the datasheet for the exact gain value.
Yes, the INA185A3IDRLT is offered in Tape & Reel (TR) and Cut Tape (CT) options, suitable for automated assembly or prototyping.
The INA254A1IPWAR is a functional peer with zero-drift architecture and 350 kHz bandwidth, but it comes in a different package (WSON) and has a higher supply current. For a pin-compatible drop-in, the INA185 family shares the same SOT-563 footprint across gain options.
