AD7887ARMZ-REEL

Overview

The AD7887ARMZ-REEL is a high-speed, low-power 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 2.7 V to 5.25 V power supply and supports throughput rates up to 125 kSPS. The device features two single-ended analog inputs configurable via an on-chip control register for either single-channel or dual-channel operation. It utilizes a successive approximation architecture with a track-and-hold circuit that acquires signals in 500 ns. The part includes a flexible serial interface compatible with SPI, QSPI, Microwire, and DSP standards. It offers multiple power management modes, including a shutdown mode with maximum current consumption of 1 μA.

Feature Summary

• Configurable single-channel or dual-channel input architecture
• Integrated internal 2.5 V reference or external reference capability
• Flexible power management with automatic shutdown options
• Versatile serial interface supporting multiple communication protocols

Applications

• Battery-powered systems such as personal digital assistants and mobile communications
• Medical instruments requiring low power consumption

• High-speed modems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with automotive qualification requirements if applicable to the target application. Cross-reference pin configurations between MSOP and SOIC packages during integration planning.

Selection Notes

Select this component for applications requiring a compact 12-bit ADC with low power dissipation. Consider the single-supply voltage range when designing power rails. Evaluate the trade-off between throughput rate and power consumption using the available standby and shutdown modes. Verify signal integrity requirements against the specified full-power bandwidth.

Part Context

This component belongs to the AD7887 series of micro-power analog-to-digital converters. It is designed for space-constrained applications due to its small 8-lead MSOP package. The series supports both commercial and automotive temperature ranges, providing flexibility for various industrial and consumer electronics environments.
