ZSSC3017 ꢀ Preliminary  
16 Bit Resistive Bridge Sensor Signal Conditioner IC  
Brief Description  
Benefits  
The ZSSC3017 is a CMOS integrated circuit for  
high accuracy amplification and analogꢀtoꢀdigital  
conversion of differential input signals. Designed  
for highꢀresolution applications, the device can  
perform offset, 1st and 2nd order span, and 1st and  
2nd order temperature (Tco and Tcg) compensation  
of the measured signal. Developed for correction  
of resistive bridge sensors, the ZSSC3017 can  
also provide a corrected temperature output using  
an internal sensor measurement. The ZSSC3017’s  
analog interface is configurable for optimizing the  
ZSSC3017's signal processing for the sensor  
element. Gain and ADCꢀinput range offset (input  
offset shift) can be programmed.  
Integrated 18ꢀbit calibration math DSP  
Fully corrected signal at digital output  
Minimize calibration costs through the oneꢀ  
pass calibration concept  
No external trimming components required  
Highlyꢀintegrated, lowꢀcost CMOS design  
Physical Characteristics  
Operation temperature: ꢀ40 to +85 °C  
Supply voltage: 2.7 to 5.5 V  
Input sensitivity: 2.44 to 0.191 ꢁV/(V*LSB)  
Sample rate: (samples/second) 200  
Sleep Mode current: <2ꢂA (25°C)  
Digital compensation of signal offset, sensitivity,  
temperature, and nonꢀlinearity is accomplished via  
an 18ꢀbitꢀwide internal digital signal processor runꢀ  
ning a correction algorithm. Calibration coefficients  
are stored in a highly reliable nonꢀvolatile memory  
(EEPROM). Measured and corrected bridge  
values are provided at the I2C™*ꢀbased digital  
output pins. Programming the ZSSC3017 is simple  
using the serial interface and the PCꢀcontrolled  
calibration software provided in the ZMDI Developꢀ  
ment Kit. The digital mating is fast and precise,  
eliminating the overhead normally associated with  
trimming external components and multiꢀpass  
calibration routines.  
Delivery options: die for wafer bonding,  
TSSOP14 package  
Applications  
Pressure measurement and control  
Mobile altimeter/barometer systems  
Weather forecasting  
Sports or multiꢀmode watches
