Current sense amp — 2 MHz bandwidth, 10 V/µs slew
The MAX4376TASA+ is a single-channel current sense amplifier from Analog Devices, designed to measure load current by amplifying the voltage drop across a sense resistor in the supply path. Its 2 MHz -3 dB bandwidth and 10 V/µs slew rate let it track fast current transients — useful for monitoring motor startup surges, short-circuit events, or dynamic load steps in a power rail.
Supply current and temperature range
Quiescent supply current is 1 mA — low enough that the amp's own draw doesn't skew the measurement on a low-side sense resistor or add noticeable overhead to a battery-powered rail. Rated from -40°C to 125°C, it covers industrial enclosures, engine-bay electronics, and outdoor telecom gear without needing a commercial-grade part swap.
Package and board-level fit
Housed in the standard 8-SOIC package (3.90 mm body width), it reuses the same footprint as generic op-amps — no custom land pattern needed for prototype or rework. Supplied in tube format — typical for small-batch builds or manual assembly; the tube quantity matches the standard SOIC-8 tube count from Analog Devices.
Lifecycle and compliance
Listed as Active with no end-of-life notice — suitable for both production and new designs without a last-time-buy clock. RoHS3 compliant (2015/863/EU), so it clears EU and UK regulatory gates without an exemption certificate.
