ICL7135CQI Description

Short technical summary and product information.

The ICL7135CQI from Analog Devices / Maxim Integrated is a monolithic 4 1/2 digit Analog-to-Digital Converter (ADC). It offers dual-slope conversion reliability with ±1 in 20,000 count accuracy and a 2.0000V full-scale capability. The device features high impedance differential inputs, nearly ideal differential linearity, true ratiometric operation, auto-zero, and auto-polarity.

 

Key electrical specifications include a ±20,000 count resolution, guaranteed ±1 count accuracy, and auto-zero accuracy better than 10µV. It operates over a temperature range of 0°C to 70°C and requires a supply voltage between 4V and 6V. The ICL7135CQI provides multiplexed BCD outputs, making it easy to interface with external display drivers or microprocessors and UARTs.

 

This ADC is suitable for a wide range of measurement applications, including voltage, resistance, and temperature measurements. It is housed in a 28-PLCC package and is designed for surface mount applications. The device also features over-range and under-range signals for auto-ranging capability.
