CS5372A

www.DataSheet4U.com CS5371A CS5372A Low-power, High-performance ∆Σ Modulators Features ‰ ‰ ‰ ‰ ‰ Description The CS5371A and CS5372A are one- and two-channel, high-dynamic-range, fourth-order ∆Σ modulators intended for geophysical and sonar applications. When combined with CS3301A / CS3302A differential amplifiers, the CS4373A test DAC and CS5376A digital filter, a small, low-power, self-testing, high-accuracy, multichannel measurement system results. The modulators have high dynamic range and low total harmonic distortion with very low power consumption. They convert differential analog input signals from the CS3301A / CS3302A amplifiers to an oversampled serial bit stream at 512 kbits per second. This oversampled bit stream is then decimated by the CS5376A digital filter to a 24-bit output at the selected output word rate. In normal operation, power consumption is 5 mA per channel. Each modulator can be independently powered down to 500 µA per channel, and by halting the input clock they will enter a micro-power state using only 2 µA per channel. The CS5371A and CS5372A modulators are available in small 24-pin SSOP packages, providing exceptional performance in a very small footprint. ORDERING INFORMATION See page 31.
