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.
