CS5372

Low-power, High-performance ∆Σ Modulators

Features & Description

Description

The CS5371 and CS5372 are one- and two-channel,

high dynamic range, fourth-order ∆Σ modulators intend-

ed for geophysical and sonar applications. Used in

combination with the CS5376A or CS5378 digital filters,

a unique high-resolution A/D measurement system

results.

z Fourth-order ∆Σ Architecture

z Clock-jitter-tolerant Architecture

z Input Voltage: 5 V Fully Differential

z High Dynamic Range

127 dB SNR @ 215 Hz BW (2 ms Output)

124 dB SNR @ 430 Hz BW (1 ms Output)

z Low Total Harmonic Distortion

The CS5371 and CS5372 have high dynamic range

(127 dB @ 215 Hz bandwidth) and low total harmonic

distortion (typically -118 dB THD), with very low power

consumption per channel. In normal mode

(LPWR=0, MCLK=2.048MHz), power consumption is

25 mW per channel, and in low-power mode

(LPWR=1, MCLK=1.024MHz), power consumption is

15 mW per channel. Each modulator can be indepen-

dently powered down to 1 mW per channel, and by

halting the input clock, they will enter a micropower state

using only 10 µW per channel.

-118 dB THD Typical, -112 dB THD Maximum

z Low Power Consumption

Normal Mode: 25 mW per Channel

Low-power Mode: 15 mW per Channel

z Small Footprint, 24-pin SSOP Package

z Single- or Multi-channel System Support

1-channel System: CS5371

The modulators generate an oversampled serial bit

stream at 512 kbits per second when operated from a

clock frequency of 2.048 MHz. They are available in a

small 24-pin SSOP package, providing exceptional per-

formance in a very small footprint.

2-channel System: CS5372

3-channel System: CS5371 + CS5372

4-channel System: CS5372 + CS5372

z Single or Dual Power Supply Configurations

VA+ = +5 V; VA- = 0 V; VD = +3.3 V to +5 V

VA+ = +2.5 V;VA- = -2.5 V;VD = +3.3 V
