4 1/2 Digit, BCD Output, A/D Converter ICL7135 Digital Voltmeter Chip

The Intersil ICL7135 precision A/D converter, with its multiplexed BCD output and digit drivers, combines dual-slope conversion reliability with 1 in 20,000 count accuracy and is ideally suited for the visual display DVM/DPM market. The 2.0000V full scale capability, auto-zero, and auto-polarity are combined with true radiometric operation, almost ideal differential linearity and true differential input. All necessary active devices are contained on a single CMOS lC, with the exception of display drivers, reference, and a clock.
The ICL7135 is a high precision monolithic 41/2-digit A/D converter. … This interfacing capability makes the ICL7135 an ideal device for use in microprocessor-based data acquisition and control systems. The ICL7135 has auto-zero accuracy better than 10µV, zero drift of 0.5µV/°C, input bias current of 10pA max.
