PCM5101PW

ADCs/DACs - Special Purpose Overview

The PCM5101PW is a stereo audio digital-to-analog converter (DAC) from Texas Instruments, featuring a DirectPath output architecture that eliminates the need for external DC-blocking capacitors. It supports sampling rates up to 384 kHz with 32-bit resolution and delivers an SNR of 106 dB. The device utilizes a PCM interface for data input and operates on a single 3V supply voltage. Packaged in a 20-pin TSSOP, it integrates internal circuitry to generate symmetric output signals centered at ground potential.

ADCs/DACs - Special Purpose Feature Summary

• DirectPath Output: Eliminates external coupling capacitors via integrated charge pump for ground-centered 2VRMS output
• High Performance: 106 dB SNR and 384 kHz maximum sampling rate
• PCM Interface: Supports standard PCM data formats without requiring complex serial protocols
• Single Supply Operation: Functions efficiently on a 3V power supply

ADCs/DACs - Special Purpose Applications

• Consumer audio equipment such as CD players and media players
• Automotive infotainment systems
• Home theater receivers and amplifiers

ADCs/DACs - Special Purpose Part Context

The PCM5101PW belongs to the PCM51xx series of audio DACs. It shares architectural similarities with variants like the PCM5100A and PCM5101APWR but differs in packaging and specific interface configurations. While the PWR suffix indicates tape-and-reel packaging, the PW suffix denotes tube packaging in a TSSOP-20 form factor.
