ICL8019AMJD/HR

ADCs/DACs - Special Purpose Overview

The ICL8019AMJD/HR is a monolithic integrated circuit manufactured by Harris Corporation, classified as a special purpose ADC/DAC component. It functions as a 4-bit expandable current-switch device designed for precision analog signal processing applications. The unit operates within a supply voltage range of 4.5V to 20V and supports through-hole mounting in a 14-DIP package with a standard 0.300-inch (7.62mm) width. The component is rated for an extended industrial operating temperature range from -55°C to +125°C, ensuring reliability in demanding environments. It complies with RoHS standards for lead-free construction.

ADCs/DACs - Special Purpose Feature Summary

• Functions as a 4-bit expandable current-switch for specialized data conversion tasks
• Supports single-supply operation within a wide voltage window
• Engineered for high-temperature stability across the full industrial range

ADCs/DACs - Special Purpose Applications

• Precision analog-to-digital and digital-to-analog conversion systems
• Expandable current-steering network implementations
• Industrial instrumentation requiring wide temperature tolerance

ADCs/DACs - Special Purpose Procurement Notes

Verify that the specific suffix HR denotes the required tape-and-reel or packaging configuration if applicable, though datasheets may not explicitly detail packaging mechanics. Confirm RoHS compliance status matches project requirements, as some listings indicate non-compliance while others state compliant. Ensure the 14-DIP package dimensions align with PCB footprint constraints. Validate the manufacturer source as Harris Corporation or its successor entity Microchip for authenticity. Cross-reference the part number against official distributor catalogs to confirm availability and exact electrical specifications before ordering.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a dedicated 4-bit expandable current-switch architecture is required rather than a general-purpose DAC. The wide supply voltage range allows flexibility in power design without additional regulation stages. Consider the 14-DIP package for prototyping or low-volume production where surface-mount alternatives are unavailable. The extended temperature rating makes it suitable for harsh industrial settings. Evaluate system compatibility with current-switching topologies rather than voltage-output interfaces.

ADCs/DACs - Special Purpose Part Context

The ICL8019 series represents a family of specialized analog interface components originally developed by Harris Corporation. These devices bridge the gap between digital control logic and analog signal paths using current-switching techniques. The AMJD variant specifically utilizes a ceramic dual-in-line package, offering superior thermal performance compared to plastic equivalents. This component belongs to the broader category of special purpose data acquisition ICs, distinct from standard microcontroller peripherals.
