PCM1609A中文资料SNR 为 105dB 的 8 通道音频 DAC数据手册TI规格书

描述 Description

The PCM1609A is a CMOS, monolithic integrated circuit that features eight 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 PCM1609A accepts industry-standard audio data formats with 16- to 24-bit audio data. Sampling rates up to 200 kHz 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.
