Class AB microphone preamplifier in SC-70-5
The MAX4465EXK is a Class AB microphone preamplifier from Analog Devices, delivering a single-channel (mono) output for conditioning electret or dynamic microphone signals before feeding an ADC or line-level input. Its 2.4 V to 5.5 V supply range lets it run directly from a single Li-ion cell or a 3.3 V / 5 V rail — no extra regulator needed in the signal path. Rated for -40°C to +85°C ambient, it fits industrial sensor interfaces, portable audio recorders, and voice-command front ends that see temperature swings.
Package and footprint for assembly
Housed in the 5-lead SC-70-5 (also known as SOT-353), the part shares the same 2.0 mm × 2.1 mm footprint as many op-amps and comparators — a standard land pattern that rework techs can hand-solder or hot-air replace without a dedicated stencil. Supplied in Bulk tube packaging, so the pick-and-place feeder setup is straightforward for low-to-medium volume runs; no tape-and-reel changeover needed for prototype or kitting quantities.
