AD7854AD

Overview

The AD7854AD is a high-speed, low-power 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single +3 V to +5 V power supply and supports throughput rates up to 200 kSPS. The device features a flexible parallel interface and includes self-calibration and system calibration options to maintain accuracy over time and temperature variations. It offers multiple power-down modes, including an automatic power-down after conversion mode consuming 25 μW. The component is housed in a 28-lead DIP package.

Feature Summary

Pen computers
Instrumentation and control systems

Procurement Notes

Verify the specific manufacturer part number against official Analog Devices documentation to confirm availability and exact specifications. Ensure compatibility with existing design requirements for voltage levels and interface types before procurement.

Selection Notes

Select this component for applications requiring high-speed 12-bit conversion with low power consumption. Consider the 28-lead DIP package constraints and parallel interface requirements when designing the PCB layout and system architecture.

Part Context

The AD7854AD belongs to the AD7854 family of ADCs, which also includes variants like the AD7854L optimized for lower power consumption at reduced speeds. This series is designed for portable and battery-operated applications where power efficiency and speed are critical.

Replacement Considerations

Direct replacements within the same family include the AD7854AR, AD7854ARS, and AD7854AQ. These parts share similar electrical characteristics but may differ in package type or temperature range. Verify pinout and specification compatibility before substitution.
