AD7887WARMZ

Overview

The AD7887WARMZ is a micropower, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 2.7 V to 5.25 V supply and supports throughput rates up to 125 kSPS. The device features two single-ended analog inputs and an internal 2.5 V reference or external reference capability. It utilizes a successive approximation register (SAR) architecture with a serial interface compatible with SPI, QSPI, Microwire, and DSP standards. The component is housed in an 8-lead MSOP package and is qualified for automotive applications under the AEC-Q100 standard.

Feature Summary

• Configurable dual-channel or single-channel operation via on-chip control register
• Flexible power management including automatic shutdown after conversion
• Versatile serial input/output port compatible with multiple industry-standard protocols

Applications

• Battery-powered systems such as personal digital assistants and mobile communications
• Medical instruments requiring low power consumption
• Instrumentation and control systems
• High-speed modems

Procurement Notes

Verify the specific suffix WARMZ against official documentation to confirm the automotive grade qualification and MSOP package type. Ensure that the ordering information matches the exact manufacturer part number to avoid discrepancies in temperature range or performance specifications. Cross-reference with the latest datasheet revision to confirm current availability status.

Selection Notes

Select this component when a small form factor 12-bit ADC is required for battery-operated devices. Consider the AD7887WARMZ for designs needing dual-channel sampling within an 8-lead MSOP footprint. Evaluate the power-down modes if system energy efficiency is critical. Verify that the serial interface timing requirements align with the host microcontroller capabilities.

Part Context

The AD7887 series represents a family of high-speed, low-power analog-to-digital converters designed for portable and industrial applications. The AD7887WARMZ specifically denotes the automotive-qualified version packaged in an 8-lead MSOP. This variant maintains the core performance characteristics of the standard AD7887 while meeting stricter reliability standards required for automotive environments.

Replacement Considerations

Check for AD7887 variants with different suffixes such as ARM or AR for non-automotive grades. Verify package compatibility between MSOP and SOIC_N if physical space allows. Confirm that electrical specifications remain identical before substituting.
