Maxim Integrated / Analog Devices ICL7135CQI+ ICL7135CQI+ Display Drive AD Converter 4.5 Digits Differential Parallel Uart Dual (+/-) 4 V

The ICL7135CQI+ is a 4½ digit analogue to digital converter with multiplexed BCD outputs in 28 pin PLCC package. This device is divided into analogue section and digital section. The digital section includes the counters, input and output interfaces and control logic which controls the timing of each measurement cycle. Each measurement in divided into four phases as auto-zero(AZ), signal integrate (INT), reference deintegrate (DE) and Zero integrator (ZI). Digital section controls operation of analogue during each of these phase using counter and the state of comparator to determine when to star each of these phase. This device is used in wide range of measurement application involving manipulation and display of analogue data such as pressure, voltage, weight, resistance, temperature, speed, current and material thickness.

• Supply voltage range is 4V to 6V
• Operating temperature range from 0°C to 70°C
• Monolithic CMOS design
• Supports parallel, UART interface
• Improved 2nd source
• ±20,000 count resolution, ±1 count accuracy
• Over-range, under-range signal for auto range capability
• True differential input, zero reading for 0V input
• TTL compatible, multiplexed BCD outputs
