CS5330A/31A

8-Pin, Stereo A/D Converter for Digital Audio

Features

General Description

Single +5 V Power Supply

18-Bit Resolution

The CS5330A/31A is a complete stereo analog-to-digi-

tal converter that performs anti-alias filtering, sampling

and analog-to-digital conversion generating 18-bit val-

ues for both left and right inputs in serial form. The

output sample rate can be infinitely adjusted between

2 kHz and 50 kHz.

94 dB Dynamic Range

Linear Phase Digital Anti-Alias Filtering

–

0.05dB Passband Ripple

80dB Stopband Rejection

The CS5330A/31A operates from a single +5 V supply

and requires only 150 mW for normal operation, making

it ideal for battery-powered applications.

Low Power Dissipation: 150 mW

The ADC uses delta-sigma modulation with 128X over-

sampling, followed by digital filtering and decimation,

which removes the need for an external anti-alias filter.

The linear-phase digital filter has a passband to

21.7 kHz, 0.05 dB passband ripple and >80 dB stop-

band rejection. The device also contains a high-pass fil-

ter to remove DC offsets.
