Used in combi- nation with the CS5376 digital filter, a unique high resolution A/D measurement system results. The CS5371 and CS5372 provide higher dynamic range and lower total harmonic distortion than our industry standard CS5321 modulator, while consuming signifi- cantly less power per channel. The modulators generate an oversampled serial bit stream at 512 kbits per second when operated from a clock frequency of 2.048 MHz. The CS5371 and CS5372 are available in a small 24-pin SSOP package, providing exceptional performance in a very small footprint. In normal mode (LPWR = 0, MCLK = 2.048 MHz), power consumption is 25 mW per channel, and in low power mode (LPWR = 1, MCLK = 1.024MHz), power consump- tion is 15 mW per channel. Each modulator can be independently powered down to 1 mW per channel, and by halting the input clock the modulators enter a mi- cropower state using only 10 µW per channel.
