Single-chip electret microphone front-end
The SSM2167-1RMZ-R7 is a Class AB mono amplifier from Analog Devices that integrates the microphone bias resistor and a shutdown function into a single 10-MSOP package — a complete electret condenser microphone (ECM) interface that needs only the capsule and a couple of decoupling caps to form a voice-grade audio chain.
Active lifecycle, no allocation signal
ROHS3 compliant with no exempt substances, so it clears EU/UKCA and China RoHS without an end-of-exemption date to track. Sourced through franchised and independent channels; availability and current pricing confirmed per RFQ. No spot premium or allocation signal on this line as of the current cycle.
10-MSOP footprint and board-fit
Housed in a 10-lead MSOP with 0.50 mm pitch — the 3.00 mm × 4.90 mm body fits into space-constrained portable designs where a larger SOIC would not route.
