CA3162E

ADCs/DACs - Special Purpose Overview

The CA3162E is a monolithic Analog-to-Digital Converter (ADC) manufactured by Intersil Corporation, utilizing I2L technology. It provides a 3-digit multiplexed BCD output designed for use with the CA3161E decoder/driver to implement complete display systems. The device features dual-slope A/D conversion and an ultra-stable internal bandgap voltage reference. It supports differential inputs and can read voltages down to 99mV below ground when powered by a single supply. Internal timing eliminates the need for external clocks, offering selectable low-speed (4Hz) or high-speed (96Hz) conversion rates.

ADCs/DACs - Special Purpose Procurement Notes

Verify manufacturer origin as Intersil Corporation or successor entities like Renesas Technology Corp. Confirm package type and temperature range specifications against original datasheets. Ensure compatibility with required driver ICs such as the CA3161E for proper BCD decoding and segment driving functionality in final assembly.

ADCs/DACs - Special Purpose Selection Notes

Select the CA3162E for applications requiring simple 3-digit display interfacing without complex microcontroller overhead. Choose this component over the CA3162AE if standard commercial temperature ranges suffice, as the AE variant offers extended temperature capabilities. Ensure input signal levels remain within the specified differential range for accurate conversion results.

ADCs/DACs - Special Purpose Part Context

This component belongs to the CA316x series of A/D converters developed by Intersil. It is specifically engineered to work in tandem with the CA3161E BCD-to-Seven-Segment Decoder/Driver.
