Current sense amp in a SOT-23-5 — what the ratings mean
The INA281A4IDBVR: The 900 kHz gain-bandwidth product and 2.5 V/µs slew rate give it enough speed to track PWM ripple and short-circuit events in switching power stages without excessive delay. 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.
