The PCM3002 and PCM3003 are low-cost, single-chip stereo audio codecs (analog-to-digital and digital-to-analog converters) with single-ended analog voltage input and output.
The PCM3002 and PCM3003 are low‑cost, high‑performance single‑chip stereo audio codecs that integrate 20‑bit ΔΣ ADC and DAC functions. PCM3002 is software‑controlled while PCM3003 is hardware‑controlled, supporting both DVC and DSC applications. Features include 16/20‑bit input/output data, multiple audio data formats, digital de‑emphasis, attenuation, and soft‑mute.
The document details electrical characteristics, absolute maximum ratings, pin assignments, typical performance curves, and packaging information. It also lists supply requirements, power consumption, and mechanical drawing data for the 24‑pin SSOP package.
