Description
The CS5501 and CS5503 are CMOS A/D converters
ideal for measuring low-frequency signals representing
physical, chemical, and biological processes. They uti-
lize charge-balance techniques to achieve 16-bit
(CS5501) and 20-bit (CS5503) performance with up to 4
k
Sps
word rates.
The converters continuously sample at a rate set by the
user in the form of either a CMOS clock or a crystal. On-
chip digital filtering processes the data and updates the
output register at up to a 4 k
Sps
rate. The converters' low-
pass, 6-pole Gaussian response filter is designed to al-
low corner frequency settings from 0.1 Hz to 10 Hz in the
CS5501 and 0.5 Hz to 10 Hz in the CS5503. Thus, each
converter rejects 50 Hz and 60 Hz line frequencies as
well as any noise at spurious frequencies.
The CS5501 and CS5503 include on-chip self-calibra-
tion circuitry which can be initiated at any time or
temperature to insure offset and full-scale errors of typi-
cally less than 1/2 LSB for the CS5501 and less than
4 LSB for the CS5503. The devices can also be applied
in system calibration schemes to null offset and gain er-
rors in the input channel.
Each device's serial port offers two general purpose
modes of operation for direct interface to shift registers
or synchronous serial ports of industry-standard micro-
controllers. In addition, the CS5501's serial port offers a
third,
UART-compatible
communication.
