ES7134 8-pin, 24-Bit, 192 KHz Stereo D/A Converter for PCM Audio GENERAL DESCRIPTION The ES7134 is a low cost 8-pin stereo digital to analog converter. The ES7134 can accept I²S serial audio data format up to 24-bit word length. The device uses advanced multi-bit ∆-∑ modulation technique to convert data into two channel analog outputs. The multi-bit ∆-∑ modulator makes the device with very low sensitivity to clock jitter and very low out of band noise.
