The CS5371A and CS5372A are single-/dual-channel, high dynamic range, fourth-order Delta-Sigma modulators intended for geophysical and sonar applications. Used in combination with the CS5376A or CS5378 digital filter, a unique high-resolution analog-to-digital measurement system results. The CS5371A and CS5372A provide higher dynamic range and lower total harmonic distortion than our industry standard CS5321 modulator, while consuming significantly less power per channel. The modulators generate an oversampled serial bit-stream at 512 K bits per second when operated from a clock frequency of 2.048 MHz. The CS5371A and CS5372A are available in a small, 24-pin SSOP package, providing exceptional performance in a very small footprint. In normal mode, power consumption is 25 mW per channel, in sleep mode power consumption is 1 mW per channel and by halting the input clock to the modulators the device enters a power-down mode of only 10 µW per channel. |
