Overview
The PCM4104PFBTG4, produced by Texas Instruments, is a high-performance, four-channel digital-to-analog (D/A) converter designed for use in professional audio applications. It supports 16- to 24-bit linear PCM input data with sampling frequencies up to 216kHz, making it ideal for high channel count applications due to its lower power consumption compared to most comparable stereo audio D/A converters. The device features a delta-sigma architecture with a high-performance multi-level modulator and a switched capacitor output filter, which yields lower out-of-band noise and high tolerance to system clock phase jitter.
