Description
The CS4373 is a differential output digital-to-
analog converter intended for high-resolution,
low-frequency measurement systems. It is de-
signed to work with the CS5376A and CS5378
digital filters, the CS3301 and CS3302 high-pre-
cision amplifiers, and the CS5371 or CS5372
high-performance
Σ
modulators.
The CS4373 includes a set of multiplexed out-
puts which provide a precision output (OUT±) for
testing the electronics channel and a buffered
output (BUF±) for in-circuit sensor tests. It is driv-
en by a
Σ
bitstream and the maximum analog
output is differential 5 volts peak-to-peak. Distor-
tion performance of the DAC is typically -118 dB
THD from the precision output, and -100 dB THD
from the buffered output. Noise performance is
114 dB SNR over a 430 Hz bandwidth.
The CS4373 has very low power consumption. In
normal mode (LPWR=0; MCLK=2.048 MHz),
power consumption is 40 mW; while in Low Pow-
er mode (LPWR=1; MCLK=1.024 MHz), power
consumption is 25 mW.
