FEATURES

ADC

DESCRIPTION

The PA5750 is a high performance, low power and

low cost Audio CODEC.

• 24-bit, 8 – 96 kHz sampling frequency

• 92dB dynamic range, 92dB signal to noise ratio,

-85dB THD+N

It consists of 2-channel ADC, 2-channel DAC,

microphone amplifier, Speaker amplifier, headset

amplifier, digital enhancements and analog mixing

and amplification functions.

• Stereo or Mono microphone interface with

microphone amplifier

• Auto level control and noise gate

• 3 to1 analog input selection

• Analog input mixers and amplifiers

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.

DAC

• 24-bit, 8 – 96 kHz sampling frequency

• 93dB dynamic range, 93dB signal to noise ratio,

-81dB THD+N

• 500mWatt speaker amplifier

• 40mWatt headphone option, pop free, capless opt.

• Stereo enhancement

• Bass and Treble

• Analog output mixers and amplifiers.

Low Power

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.

• 1.8 to 3.3Volt operation

• 7mWatt playback, 16mWatt playback and record.

System

The PA5750 operates from 1.8V to 3.6V. Sections

of the chip can be powered down by software

control.

• I²C or SPI µC interface

• Headphone Detector

• 256Fs, 384Fs, USB 12MHz or 24MHz

• Master or Slave serial port

• I²S, Left Justified, DSP/PCM Mode

The PA5750 is offered in a 5x5mm QFN Package
