Product details

The Texas Instruments INA180B2IDBVR is a single-channel current-sense amplifier in a SOT-23-5 package. It measures current across a shunt resistor and outputs a rail-to-rail voltage proportional to the sensed current. Bandwidth is 350 kHz.

Active production — no PCN watch needed

The base product number INA180 spans multiple gain options (, variants) in the same SOT-23-5 footprint, so a gain change mid-cycle requires only a different suffix — no board respin.

Sourcing this line item

For a BOM freeze or a production replenishment, submit an RFQ with your target quantity and date-code window. The SOT-23-5 package is standard for automated pick-and-place; tape-and-reel quantities are the norm, but cut-tape samples can be quoted for prototype builds.

Frequently asked questions

What is the output type of INA180B2IDBVR?

The output is rail-to-rail, meaning the voltage can swing from near the negative supply to near the positive supply. This maximizes the dynamic range when driving an ADC or comparator input.

Does INA180B2IDBVR have an equivalent or replacement?

The INA180B2IDBVR is an active part with no direct replacement listed by TI. The INA254A1IPWAR is a zero-drift current-sense amp in the same bandwidth class, but it uses a different architecture (zero-drift chopper) and a different package — verify pin compatibility before substituting. The INA4290A2IRGVR is a quad-channel part with 1.1 MHz bandwidth but a different pinout and package. Neither is a drop-in replacement.

Is INA180B2IDBVR single or dual supply?

The INA180B2IDBVR operates from a single supply rail between 2.7 V and 5.5 V. It is not a dual-supply device; the negative rail is ground.
