Description
The CS5516 and CS5520 are complete solutions for dig-
itizing low level signals from strain gauges, load cells,
and pressure transducers. Any family of mV output
transducers, including those requiring bridge excitation,
can be interfaced directly to the CS5516 or CS5520. The
devices offer an on-chip software programmable instru-
mentation amplifier block, choice of DC or AC bridge
excitation, and software selectable reference and signal
demodulation.
The CS5516 uses delta-sigma modulation to achieve
16-bit resolution at output word rates up to 60 Hz. The
CS5520 achieves 20-bit resolution at word rates up to
60 Hz.
The CS5516 and CS5520 sample at a rate set by the
user in the form of either an external CMOS clock or a
crystal. On-chip digital filtering provides rejection of all
frequencies above 12 Hz for a 4.096 MHz clock.
The CS5516 and CS5520 include system calibration to
null offset and gain errors in the input channel. The digi-
tal values associated with the system calibration can be
written to, or read from, the calibration RAM locations at
any time via the serial communications port. The 4-bit
DC offset D/A converter, in conjunction with digital cor-
rection, is initially used to zero the input offset value.
