Overview

The PCM1808PWR is a high-performance, low-cost single-chip stereo analog-to-digital converter from Texas Instruments. It features a 24-bit Delta-Sigma architecture with 96 kHz sampling support, making it suitable for a wide range of consumer audio applications requiring high-resolution digital conversion.

Why Choose This Part

The device offers excellent power efficiency, consuming only 8.6 mA for the analog supply at 48 kHz. Its integrated high-pass filter and antialiasing low-pass filter simplify the front-end design by reducing the need for external filtering components.

Applications

AV Receivers
Converting analog stereo signals from legacy media players or tuners into digital formats for DSP processing.
Digital Voice Recorders
Capturing high-fidelity audio in portable devices with low power consumption requirements.
Musical Instruments
Integrating into digital keyboards or synthesizers to digitize analog line-level signals.
Soundcards and Audio Interfaces
Serving as the primary input stage for entry-level professional and semi-professional recording hardware.
