CS5501  
CS5503  
Low-Cost, 16 & 20-Bit Measurement A/D Converter  
Features  
Description  
The CS5501 and CS5503 are low-cost CMOS A/D con-  
verters ideal for measuring low-frequency signals  
representing physical, chemical, and biological process-  
es. They utilize charge-balance techniques to achieve  
16-bit (CS5501) and 20-bit (CS5503) performance with  
up to 4 kHz word rates at very low cost.  
Monolithic CMOS ADC with Filtering  
- 6-Pole, Low-Pass Gaussian Filter  
Up to 4 kHz Output Word Rates  
- On Chip Self-Calibration Circuitry  
- Linearity Error: ±0.0003%  
- Differential Nonlinearity:  
CS5501: 16-Bit No Missing Codes  
(DNL ±1/8 LSB)  
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 kHz 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.  
CS5503: 20-Bit No Missing Codes  
System Calibration Capability  
Flexible Serial Communications Port  
- µC-Compatible Formats  
- 3-State Data and Clock Outputs  
- UART Format (CS5501 only)  
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.  
Pin-Selectable Unipolar/Bipolar Ranges  
Low Power Consumption: 25 mW  
- 10 µW Sleep Mode for Portable Applications  
Evaluation Boards Available  
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 mode of asynchronous  
communication.
