Product details

Bandwidth and slew rate — what they mean for your loop

At 1 MHz bandwidth, the part can track current changes in switching regulators and motor drives. The 2.5 V/µs slew rate supports feeding a comparator or ADC input.

Package and mounting — fits tight boards

The SOT-23-5 footprint is a standard surface-mount package. The part is available on Tape & Reel or Cut Tape.

Lifecycle and sourcing — active, no LTB concern

The INA293B3IDBVT carries an active lifecycle status and is ROHS3 compliant. It is sourced through independent distribution and quoted to order.

Frequently asked questions

What is the bandwidth of INA293B3IDBVT?

The -3 dB bandwidth is 1 MHz, with a slew rate of 2.5 V/µs. This is suitable for switching power supply and motor drive current feedback loops.

What are popular alternatives to INA293B3IDBVT?

A close functional peer is the INA254A1IPWAR, also a single-channel current-sense amplifier with zero-drift architecture, 350 kHz bandwidth, 2.4 V/µs slew rate, and the same 2.7 V minimum supply and -40°C to 125°C range. The INA4290A2IRGVR is a quad-channel option with 1.1 MHz bandwidth and 2 V/µs slew rate. Neither is a direct pin-for-pin replacement; verify the pinout and package before substituting.
