PCM1602 (NRND)

105dB SNR 6-Channel Audio DAC

 

Not Recommended for New Designs (NRND)

Replaced By PCM1602A– The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

Description

The PCM1602 is a CMOS, monolithic integrated circuit that features six 24-bit audio digital-to-analog converters (DACs) and support circuitry in a small LQFP-48 package. The DACs use Texas Instruments' enhanced multilevel, delta-sigma architecture that employs fourth-order noise shaping and 8-level amplitude quantization to achieve excellent signal-to-noise performance and a high tolerance to clock jitter.

The PCM1602 accepts industry-standard audio data formats with 16- to 24-bit audio data. Sampling rates up to 200 kHz (channels 1 and 2) or 100 kHz (channels 3, 4, 5, and 6) are supported. A full set of user-programmable functions is accessible through a 4-wire serial control port that supports register write and read functions.
