AD9023AZ

Overview

The AD9023AZ is a high-speed, monolithic 12-bit analog-to-digital converter manufactured by Analog Devices Inc. It integrates essential functions including a track-and-hold circuit and three A/D converters within a single chip. The device supports parallel word access for efficient data transfer. It operates within a supply voltage range of -5.45V to -4.95V for analog sources and 4.75V to 5.25V for digital logic. The component features a single-ended input type and is housed in a 28-CDIP package with dimensions of 0.600 inches (15.24mm). It maintains reliable performance across an operating temperature range from -25°C to +85°C.

Feature Summary

• Integrates track-and-hold functionality directly on the monolithic die
• Provides parallel word access interface for rapid data retrieval
• Contains three distinct analog-to-digital conversion channels

Applications

• High-speed data acquisition systems requiring parallel output
• Industrial instrumentation utilizing single-ended signal inputs
• Test and measurement equipment needing 12-bit resolution

Procurement Notes

Verify the specific manufacturer source when sourcing this component, as historical records indicate production by entities such as Hitech Semiconductor or Rochester Electronics alongside Analog Devices. Confirm the package style matches the required 28-CDIP footprint. Ensure that the supply voltage requirements align with the specified negative analog rails and positive digital logic levels before integration into the design.

Selection Notes

Select this component for applications demanding high-speed conversion with a 12-bit resolution profile. The integrated track-and-hold feature simplifies external circuitry requirements compared to discrete solutions. Consider the single-ended input configuration when designing front-end conditioning stages. The wide operating temperature range supports deployment in varied environmental conditions without additional thermal management.

Part Context

This part belongs to the broader category of analog-to-digital converters designed for precision and speed. Unlike display drivers found in other series, this unit focuses strictly on signal digitization. The 28-CDIP package offers robust mechanical stability for through-hole mounting. It serves as a critical interface between analog sensor outputs and digital processing units in complex electronic architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 12-bit resolution, parallel interface, and 28-CDIP package constraints. Verify pin compatibility and electrical specifications with potential alternatives before implementation.
