General Description

The PA5750 is a high performance, low power and low cost Audio CODEC.

It consists of 2-channel ADC, 2-channel DAC, microphone amplifier, Speaker amplifier, headset amplifier, digital enhancements and analog mixing and amplification functions.

The PA5750 uses advanced multi-bit delta-sigma modulation techniques to convert DATA between digital and analog. The multi-bit delta-sigma modulations decrease the sensitivity to clock jitter and low out of band noise.

The PA5750 can operate as the Master or the Slave with various clock frequencies including 12 or 24MHz for USB devices. Audio sample rates (44.1, 48 and 96kHz) are generated directly from the master clock.

The PA5750 operates from 1.8V to 3.6V. Sections of the chip can be powered down by software control.

The PA5750 is offered in a 5x5mm QFN Package
