WM8524CGEDT/R 24位立体声数字音频转换器芯片简介

DESCRIPTION The WM8524 is a stereo DAC with integral charge pump and hardware control interface. This provides 2Vrms line driver outputs using a single 3.3V power supply rail. The device features ground-referenced outputs and the use of a DC servo to eliminate the need for line driving coupling capacitors and effectively eliminate power on pops and clicks. The device is controlled and configured via a hardware control interface. The device supports all common audio sampling rates between 8kHz and 192kHz using all common MCLK fs rates. The audio interface operates in slave mode. The WM8524 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected. The device is available in a 16-pin TSSOP. FEATURES ?
