PCM5100A

Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This TI datasheet covers the PCM510xA family of stereo digital-to-analog converters, including variants 0A, 1A, and 2A, along with their automotive Q1 versions. The document details features like Directpath charge-pump technology, an integrated high-performance audio PLL, and intelligent muting systems that eliminate the need for DC-blocking capacitors. Key performance parameters include ultra-low out-of-band noise, line-level RMS outputs down to 1kΩ loads, and support for 32-bit, 384 kHz PCM data formats in I2S or left-justified modes. These devices operate on a single supply of 1.8V to 3.3V and are designed for applications ranging from A/V receivers and DVD players to automotive infotainment and aftermarket amplifiers.
