AD7892AR-1REEL

Overview

The AD7892AR-1REEL is a 12-bit successive approximation analog-to-digital converter (ADC) fabricated in Analog Devices' LC2MOS process. It operates from a single +5 V supply and supports throughput rates of 500 kSPS with a conversion time of 1.6 µs. The device features an on-chip track/hold amplifier, an internal +2.5 V reference, and versatile interface structures allowing both parallel and serial connections to microprocessors. It accepts analog input ranges of ±10 V or ±5 V and includes overvoltage protection on the analog inputs.

Feature Summary

• Single-supply operation with low power consumption
• Integrated track/hold amplifier and internal voltage reference
• Flexible parallel and serial data output interfaces
• Overvoltage protection on analog input pins

Applications

• Portable instrumentation systems
• Industrial process control loops
• Data acquisition modules

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range for your design. Confirm the presence of the REEL designation indicates tape-and-reel packaging rather than tube packaging. Ensure the component version aligns with the intended input voltage range specifications before finalizing procurement orders.

Selection Notes

Select this model when a 500 kSPS sampling rate and ±10 V or ±5 V input range are required. Consider the SOIC package format for surface-mount assembly needs. Evaluate the internal reference stability against external precision requirements if tighter tolerance is necessary for the application.

Part Context

This component belongs to the AD7892 family of high-speed, low-power ADCs. Variants within the series differ primarily by input voltage range capabilities and maximum throughput speeds. The AD7892-1 specifically targets bipolar input applications requiring robust signal scaling from a single supply.

Replacement Considerations

Direct substitutes include other AD7892 variants such as AD7892BRZ-1REEL or AD7892AN-1Z, provided the package style and temperature grade match the system requirements.
