信息

The CS4234 is a highly versatile CODEC that combines 4 channels of high performance analog to digital conversion, 4 channels of high performance digital to analog conversion for audio, and 1 channel of digital to analog conversion to provide a nondelayed audio reference signal to an external Class H tracking power supply. If not used to drive a tracking power supply, the 5th DAC can instead be used as a standard audio grade DAC, with performance specifications identical to that of the 4 DACs in the audio path. Additionally, the CS4234 includes tunable group delay for each of the 4 audio DAC paths to provide lead time for the external switch-mode power supply, and a nondelayed path into the DAC outputs for input signals requiring a low-latency path to the outputs. Targeting the automotive audio market, this controller was specifically designed to work with Apex Precision Power’s CS44417 Class AB audio amplifier, but remains flexible enough to allow any standard Class AB amplifier to be operated as a Class H amplifier in order to maximize efficiency. Class H control provides significant efficiency gains over traditional Class AB amplifiers, while avoiding the increased electromagnetic interference (EMI) and cost of Class D amplifiers.
