Packaged in a 5-pin SOT-23-5, it fits tight PCB layouts but demands careful Kelvin routing of the sense lines to the shunt — the 20 µA input bias current is low enough that a few ohms of trace resistance won't skew the reading, but the sense resistor's own tolerance dominates the gain error. The 900 kHz gain-bandwidth product and 2.5 V/µs slew rate allow tracking PWM ripple and short-circuit events in switching power stages. The ROHS3 compliance is current — no exemption expiry concerns for EU markets.","metaTitle":"INA281A4IDBVR Current Sense Amplifier, 900 kHz, SOT-23-5","metaDescription":"TI INA281A4IDBVR current sense amplifier: 2.7 V to 20 V supply, 900 kHz GBW, 2.5 V/µs slew rate, -40°C to 125°C.

The zero-drift architecture gives it lower input offset drift over temperature, which matters for precision DC measurement. The INA281A4IDBVR's 900 kHz bandwidth makes it a better fit when you need to track faster current transients."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA281A4IDBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA281A4IDBVR when reusing this data.
