PA5331

Low Power 24-Bit, Stereo Audio CODEC

With Headphone Amplifier

ANALOG PRODUCTS DIVISION

FEATURES

GENERAL DESCRIPTION

ADC

24-bit, 8 kHz to 96 kHz sampling frequency

The PA5331 is a high performance, low power and low cost

audio CODEC. It consists of 2-ch ADC, 2-ch DAC,

microphone amplifier, headphone amplifier, digital sound

effects, and analog mixing and gain functions.

95 dB dynamic range, 95 dB signal to noise ratio, -85 dB

THD+N

Stereo or mono microphone interface with microphone

amplifier

Auto level control and noise gate

3-to-1 analog input selection

The PA5331 uses advanced multi-bit delta-sigma modulation

technique to convert data between digital and analog.

Various analog input mixing and gains

DAC

The multi-bit delta-sigma modulators make the device with low

sensitivity to clock jitter and low out of band noise.

24-bit, 8 kHz to 96 kHz sampling frequency

96 dB dynamic range, 96 dB signal to noise ratio, -83 dB

THD+N

40 mW headphone amplifier, pop noise free

Stereo enhancement

Bass and Treble

Various analog output mixing and gains

LOW POWER

1.8V to 3.3V operation

7 mW playback; 16 mW playback and record
