CS5516  
CS5520  
16-Bit/20-Bit Bridge Transducer A/D Converter  
Features  
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.  
l On-chip Instrumentation Amplifier  
l On-chip Programmable Gain Amplifier  
l On-Chip 4-Bit D/A For Offset Removal  
l Dynamic Excitation Options  
l Linearity Error: ±0.0015% FS  
- 20-Bit No Missing Codes  
l CMRR at 50/60 Hz > 200 dB  
l System Calibration Capability with calibration  
read/write option  
l 3, 4 or 5 wire Serial Communications Port  
l Low Power Consumption: 40 mW  
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.  
- 10 µW Standby Mode for Portable applications  
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.
