Description
The CS5373A is a high-performance, fourth-order
Σ
modulator integrated with a
Σ
digital-to-analog convert-
er (DAC). When combined with a CS3301A / CS3302A
differential amplifier and the CS5378 digital filter, a
small, low-power, self-testing, high-accuracy, single-
channel measurement system results.
The modulator has high dynamic range and low total har-
monic distortion with very low power consumption. It
converts differential analog input signals from the
CS3301A / CS3302A amplifier to an oversampled serial
bit stream at 512 kbits per second. This oversampled bit
stream is then decimated by the CS5378 digital filter to a
24-bit output at the selected output word rate.
The test DAC operates in either AC or DC test modes.
AC test modes measure system dynamic performance
through THD and CMRR tests while DC test modes are
for gain calibration and pulse tests. It has two sets of dif-
ferential analog outputs,
OUT
and
BUF
, as dedicated
outputs for testing the electronics channel and for in-
circuit sensor tests. Output attenuation settings are
binary weighted and match the gain settings of the
CS3301A / CS3302A differential amplifiers for full-scale
testing at all gain ranges.
