PCM1690
Description
The PCM1690 device is a high-performance, singlechip, 24-bit, eight-channel, audio digital-to-analog converter (DAC) with differential outputs. The eightchannel, 24-bit DAC employs an enhanced, multilevel delta-sigma (ΔΣ) modulator and supports 8-kHz to 192-kHz sampling rates and a 16-/20-/24-/32-bit width digital audio input word on the audio interface.
