The PCM3000/3001 is a low-cost, single-chip stereo audio codec with single-ended analog voltage input and output. Both ADCs and DACs employ delta-sigma modulation with 64-times oversampling. The codec is suitable for various audio applications including recording devices, karaoke systems, and car stereos.
The PCM3000 and PCM3001 are low‑cost, single‑chip 18‑bit stereo audio codecs that provide both analog‑to‑digital and digital‑to‑analog conversion with single‑ended voltage inputs and outputs. They are offered in a compact 28‑pin SSOP package and target cost‑sensitive consumer audio applications such as car stereos, digital mixers, and karaoke systems.
The datasheet includes full electrical characteristics, recommended operating conditions, pin assignments, mechanical dimensions, and performance curves. It also lists absolute maximum ratings, power‑supply requirements, and ordering information for both devices.
