General Description
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.
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.
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.
The device is available in an 8-pin SOIC package in
both Commerical (
-10° to +70° C) and Automotive grades
(- 40° to +85° C)
. Please refer to “Ordering Information”
on page 16 for complete details.
