Audio signal path fit and key parametrics
The OPA1671IDCKT: With a 13 MHz gain bandwidth product and a 5V/µs slew rate, the amplifier maintains linearity across the full audio band (20 Hz–20 kHz) with enough headroom for transient peaks without slew-induced distortion. Rail-to-rail output swing lets the signal use the full supply range, which matters in single-supply designs where headroom is tight — the output can swing within millivolts of each rail.
Quiescent supply current is 940 µA per channel, keeping the thermal footprint low in dense boards where multiple amplifiers share a small copper area.
Package and board integration
Housed in a 5-pin SC-70-5 (SOT-353) package, the OPA1671IDCKT occupies roughly 2 mm × 2 mm of board area — a fit for space-constrained audio codec front-ends or portable recorder input stages. Surface-mount assembly with tape-and-reel packaging (Cut Tape also available) means it feeds into standard pick-and-place lines without manual handling.
Lifecycle and compliance status
ROHS3 compliant per the latest exemption list, so it passes into European and California-restricted markets without a waiver.
