Description
The CS5371A and CS5372A are one- and two-channel,
high-dynamic-range, fourth-order
Σ
modulators intend-
ed for geophysical and sonar applications. When
combined with CS3301A / CS3302A differential amplifi-
ers, the CS4373A test DAC and CS5376A digital filter, a
small, low-power, self-testing, high-accuracy, multi-
channel measurement system results.
The modulators have high dynamic range and low total
harmonic distortion with very low power consumption.
They convert differential analog input signals from the
CS3301A / CS3302A amplifiers to an oversampled seri-
al bit stream at 512 kbits per second. This oversampled
bit stream is then decimated by the CS5376A digital filter
to a 24-bit output at the selected output word rate.
In normal operation, power consumption is 5 mA per
channel. Each modulator can be independently powered
down to 500 μA per channel, and by halting the input
clock they will enter a micro-power state using only 2 μA
per channel.
The CS5371A and CS5372A modulators are available in
small 24-pin SSOP packages, providing exceptional per-
formance in a very small footprint.
