Information

The CS4207 is a highly integrated multi-channel lowpower HD Audio Codec featuring 192 kHz DACs, 96 kHz ADCs, 192 kHz S/PDIF Transmitters and Receiver, Microphone pre-amp and bias voltage, and a ground centered Headphone driver. Based on multi-bit, delta-sigma modulation, it allows infinite sample rate adjustment between 32 kHz and 192 kHz. The ADC input path allows control of a number of features. The microphone input path includes a selectable programmable-gain pre-amplifier stage and a low-noise MIC bias voltage supply. A PGA is available for line and microphone inputs and provides analog gain with soft ramp and zero cross transitions. The ADC also features an additional digital volume attenuator with soft ramp transitions. The stereo headphone amplifier is powered from a separate internally generated positive supply, with an integrated charge pump providing a negative supply. This allows a ground-centered analog output with a wide signal swing and eliminates external DC-blocking capacitors. The integrated digital audio interface receiver and transmitters utilize a 24-bit, high-performance, monolithic CMOS stereo asynchronous sample rate converter to clock align the PCM samples to/from the S/PDIF interfaces. Auto detection of non-PCM encoded data disables the sample rate conversion to preserve bit accuracy of the data. In addition to its many features, the CS4207 operates from a low-voltage analog and digital core, making this part ideal for portable systems that require low power consumption in a minimal amount of space. The CS4207 is available in a 48-pin WQFN package in both Automotive (-40°C to +105°C) and Commercial (-40°C to +85°C) grades.
