The PCM1609A is a 8-channel 24-bit audio digital-to-analog converter (DAC) produced by Texas Instruments. It uses an enhanced multilevel, delta-sigma architecture with fourth-order noise shaping and 8-level amplitude quantization to achieve excellent signal-to-noise performance and a high tolerance to clock jitter.
The PCM1609A is a CMOS monolithic integrated circuit featuring eight 24-bit audio digital-to-analog converters (DACs) and support circuitry in an LQFP-48 package. It utilizes Texas Instruments' enhanced multilevel, delta-sigma architecture employing fourth-order noise shaping and 8-level amplitude quantization to achieve excellent signal-to-noise performance.
