PCM5102PW

PCM5102PW Description

The PCM5102PW from Texas Instruments is a high-performance stereo digital-to-analog converter (DAC) designed for premium audio applications. Part of the DirectPath™ series, this IC supports 16-bit, 24-bit, and 32-bit resolutions with a sampling rate up to 384 kHz, ensuring high-fidelity audio reproduction. It operates on a 3V to 3.6V dual-supply (analog and digital) and is housed in a 20-pin TSSOP package, making it suitable for space-constrained designs. Although marked as "Not For New Designs", it remains a reliable choice for legacy systems requiring low-noise, high-resolution audio conversion.
