ICL7135CPI+ by Analog Devices

4 1/2 Digit ADC with Multiplexed BCD Outputs


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 Active-Low STROBE, OVERRANGE, UNDERRANGE, RUN/Active-Low HOLD and BUSY lines providing easy interface to microprocessors and UARTs. 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. and rollover error of less than 1 count.
