CS5330A/31A 8-Pin, Stereo A/D Converter for Digital Audio Single +5 V Power Supply 18-Bit Resolution 94 dB Dynamic Range Linear Phase Digital Anti-Alias Filtering dB Passband Ripple 80 dB Stopband Rejection Low Power Dissipation 150 mW Power-Down Mode for Portable Applications Complete CMOS Stereo A/D System Delta-Sigma A/D Converters Digital Anti-Alias Filtering S/H Circuitry and Voltage Reference Adjustable System Sampling Rates including 32, and 48 kHz The CS5330A/31A is a complete stereo analog-to-digital converter that performs antialias filtering, sampling and analog-to-digital conversion generating 18-bit values 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 oversampling, 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 kHz, dB passband ripple and >80 dB stopband rejection. The device also contains a high-pass filter to remove DC offsets. The device is available in an 8-pin SOIC package in both Commercial -10° to +70° C and Automotive grades -40° to +85° C . Please refer to “Ordering Information” on page 16 for complete details.

A 47 resistor on this pin will place the CS5330A/31A into Master Mode. Serial Data Clock Input/Output - SCLK is an input clock at any frequency from 32x to 64x the 2 output word rate. SCLK can also be an output clock at 64x if in the Master Mode. Data is clocked out on the falling edge of SCLK. Left/Right Clock Input/Output - LRCK selects the left or right channel for output on SDATA. The LRCK frequency must be at the output sample rate. LRCK is an output clock if in Master 3 Mode. Although the outputs of each channel are transmitted at different times, the two words in an LRCK cycle represent simultaneously sampled analog inputs. Master Clock Input - Source for the delta-sigma modulator sampling and digital filter clock. Sample rates and digital filter characteristics scale to the MCLK frequency. Analog Right Channel Input - Analog input for the right channel. Typically 4 Vpp for a full-scale input signal. 6 Analog Ground Input - Analog ground reference. 7 Positive Analog Power Input - Positive analog supply Nominally +5 V . Analog Left Channel Input - Analog input for the left channel. Typically 4 Vpp for a fullscale input signal.
