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.
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.
