CS5371/CS5372

Low-Power High-Performance ∆Σ Modulators

Features

Description

The CS5371 and CS5372 are one and two channel high

dynamic range, fourth-order ∆−Σ modulators intended

for geophysical and sonar applications. Used in combi-

nation with the CS5376 digital filter, a unique high

resolution A/D measurement system results.

l Fourth-Order ∆Σ Architecture

l Clock Jitter Tolerant Architecture

l Input Voltage Range 5 V (2.5 V

)

l High Dynamic Range (SNR)

s 124 dB @ 411 Hz Bandwidth

s 121 dB @ 822 Hz Bandwidth

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.

l Low Total Harmonic Distortion (THD)

s -118 dB Typical, -112 dB Maximum

l Low Power Consumption

s Normal Mode:

25 mW per Channel

s Low Power Mode: 15 mW per Channel

l Small Footprint 24 Pin SSOP Package

l Single or Multi-Channel System Support

s 1 Channel System; CS5371

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.

s 2 Channel System; CS5372

s 3 Channel System; CS5371 + CS5372

s 4 Channel System; CS5372 + CS5372

l Single or Dual Power Supply Configurations

s VA+ = +5 V; VA- = 0 V;

s VA+ = +2.5 V; VA- = -2.5 V; VD = +3 V to +5 V

s VA+ = +3 V; VA- = -3 V;

VD = +3 V to +5 V
