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 Sps. The

CS5520 achieves 20-bit resolution at output word rates

up to 60 Sps.

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.
