PCM1801U/2K Description

Short technical summary and product information.

The Texas Instruments PCM1801U/2K is a cost-effective, single-chip stereo analog-to-digital converter (ADC) designed for audio applications. It features single-ended analog voltage inputs and a 16-bit resolution, providing a typical Signal-to-Noise Ratio (SNR) of 93dB and a Total Harmonic Distortion plus Noise (THD+N) of -88dB.

 

This ADC utilizes a delta-sigma modulator with 64x oversampling and includes an integrated antialiasing filter and decimation filter. It supports PCM audio interfaces, including Left-Justified and I2S, with sampling rates ranging from 4kHz to 48kHz. The device operates from a single 5V power supply and requires a system clock of 256 fS, 384 fS, or 512 fS.

 

Packaged in a compact 14-SOIC (0.154", 3.90mm Width) surface-mount package, the PCM1801U/2K is suitable for a wide range of consumer electronics. Its operating temperature range is -25°C to 85°C. Applications include DVD recorders, DVD receivers, AV amplifier receivers, and electric musical instruments.
