PA5750

Low Power Stereo Audio CODEC

With Speaker and Headphone Amplifier.

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
