ICL7135 41/2 Digit A/D Converter with Multiplexed BCD Outputs General Description The Maxim ICL7135 is a high precision monolithic 41/2 digit A/D converter.
Dual slope conversion reliability is combined with ±1 in 20,000 count accuracy and a 2.
0000V full scale capability.
It features high impedance differential inputs, nearly ideal differential linearity, true ratiometric operation, auto zero and auto-polarity.
The multiplexed BCD outputs and digit drivers provide easy interface to external display drivers like the Maxim ICM7211A.
The only other external components needed to make precision DVM/DPMs are a reference and a clock.
For more complex systems the BCD outputs are enhanced by STROBE...
