Renesas (ICL7135CPIZ) Display Drive AD Converter, 4.5 Digits

Display Drive AD Converter, 4.5 Digits, 2 SPS, Differential, Serial, 4 V

Product Overview
The ICL7135CPIZ is a 4-1/2 digit BCD output 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 ratiometric operation, almost ideal differential linearity and true differential input. All necessary active devices are contained on a single CMOS IC, with the exception of display drivers, reference and a clock. The ICL7135 brings together an unprecedented combination of high accuracy, versatility and true economy. It features auto-zero to less than 10µV, zero drift of less than 1µV/°C, input bias current of 10pA (maximum) and rollover error of less than one count. The versatility of multiplexed BCD outputs is increased by the addition of several pins which allow it to operate in more sophisticated systems.

Accuracy guaranteed to ±1 count over entire ±20000 counts (2.0000V full scale)
Guaranteed zero reading for 0V input
1pA Typical input leakage current
True differential input
True polarity at zero count for precise null detection
Single reference voltage required
Over range and under range signals available for auto-range capability
All outputs TTL compatible
Blinking outputs gives visual indication of over range
6 Auxiliary I/Os are available for interfacing to UARTs, microprocessors or other circuitry
Multiplexed BCD outputs

Applications
Imaging, Video & Vision
