Product details

Current-sense amplifier with 350 kHz bandwidth

It monitors current via a shunt resistor and outputs a rail-to-rail voltage proportional to the sensed current, targeting motor-drive feedback, power-supply monitoring, and battery-management loops. The -3 dB bandwidth is 350 kHz, with a slew rate of 2 V/µs — fast enough to capture PWM ripple in a 20 kHz motor drive or the load step of a switched-mode supply.

Supply rails and temperature range

The SOT-23-5 footprint matches standard land patterns for the SC-74A case, so no special pad geometry is needed for reflow.

Frequently asked questions

What is the gain of the INA180A3IDBVR?

The INA180A3IDBVR is a current-sense amplifier; its transimpedance gain is set by the external shunt resistor and the internal fixed gain. The device family includes fixed-gain variants; the A3 suffix corresponds to a gain of 100 V/V. Confirm the specific gain in the datasheet for the A3 variant.

Can the INA180A3IDBVR be used for high-side current sensing?

Yes — the INA180A3IDBVR is a current-sense amplifier that supports both high-side and low-side shunt monitoring. Its rail-to-rail output and wide common-mode range allow direct connection to the sense resistor on the high side.

What are alternatives to the INA180A3IDBVR?

No pin-compatible alternate is listed on the record. The INA180 family includes multiple fixed-gain variants in the same SOT-23-5 footprint, allowing gain selection without a PCB layout change. For a different bandwidth or supply range, consider the INA181 or INA282 series from Texas Instruments.
