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.
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 W 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. They are available in a
small 24-pin SSOP package, providing exceptional per-
formance in a very small footprint.
