Renesas Electronics 4.5 Digits Dual Slope Analogue to Digital Converter, 28-Pin PDIP ICL7135CPIZ

Renesas Electronics ICL7135CPIZ is a 4.5 digits Analogue to Digital Converter (ADC) featuring dual slope architecture, supplied in a 28-pin PDIP package. This precision ADC is engineered for high accuracy with ±1 in 20,000 count capability and multiplexed BCD outputs, designed primarily for digital meter applications requiring reliable visual display.

The device operates with a maximum supply voltage of 6V and supports differential input types, providing true polarity detection at zero count which enhances null detection precision. Its guaranteed zero reading for 0V input and the extremely low input leakage current of 1pA make it especially suited for accurate low signal measurements.

The ICL7135CPIZ packaged in a through-hole 28-pin PDIP measures 36.96 mm in length and 7.37 mm in height, fitting easily into standard PCB layouts. Its operational temperature range from 0°C to 70°C ensures dependable performance across typical environmental conditions encountered in industrial and laboratory settings.

This ADC includes useful features such as over range and under range outputs facilitating automatic range selection in measurement instruments. Visual indicators through blinking outputs alert operators to over range conditions, improving data monitoring and reducing error risks.

The component does not carry specific automotive standards or certifications but is designed for use in precision instrumentation, laboratory measurement setups, construction of digital voltmeters and digital panel meters, as well as various industrial and manufacturing process controls.
