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
