ICL7109EPL

Analog To Digital Converters (ADC) Overview

The ICL7109EPL is a monolithic 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features a dual-slope integration architecture with a differential input type and parallel interface. The device operates on a single ±5V power supply and supports a sampling rate of 30 samples per second. Packaged in a 40-PDIP through-hole format, it functions within an industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum power dissipation of 500 mW, an integral nonlinearity (INL) of +/- 1 counts, and an external reference voltage requirement of 204.8 mV.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with dual-slope integration architecture
• Parallel data interface with 3-state binary output
• Industrial temperature range (-40°C to +85°C)
• Single ±5V power supply operation

Analog To Digital Converters (ADC) Applications

• Microprocessor-based data acquisition systems
• Remote data logging applications
• High-precision panel meters

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EPL' against the manufacturer's current datasheet to confirm the exact temperature grade and package variant. Confirm RoHS compliance status for the specific batch. Check availability as distribution channels may list this component as discontinued or limited stock depending on the region.

Analog To Digital Converters (ADC) Selection Notes

Select the ICL7109EPL when a 12-bit resolution and parallel interface are required for direct microprocessor connection. Ensure the application environment stays within the -40°C to +85°C operating range. Verify that the system can provide the necessary external components, including the timing crystal and integration capacitors, as specified in the technical documentation.

Analog To Digital Converters (ADC) Part Context

The ICL7109 belongs to the ICL7109 series of 12-bit A/D converters. It is distinct from the ICL7107, which is a 3.5-digit LED display driver, and the ICL7106, which is a 3.5-digit ADC without the microprocessor interface logic. The EPL suffix denotes the PDIP-40 package and industrial temperature rating.
