AD7866BRUZ-REEL

Overview

The AD7866BRUZ-REEL is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.25 V and supports throughput rates up to 1 MSPS. The device integrates two independent ADCs with track-and-hold amplifiers capable of handling input frequencies exceeding 10 MHz. It features an internal 2.5 V reference, flexible power management modes including full shutdown, and a high-speed serial interface compatible with SPI, QSPI, and Microwire standards. The component is housed in a 20-lead TSSOP package.

Feature Summary

• Dual simultaneous sampling architecture with integrated track-and-hold amplifiers for each channel
• Flexible power management allowing operation across varying throughput rates and sleep modes
• Integrated 2.5 V reference with selectable external or internal reference configurations
• High-speed serial interface supporting standard microprocessor and DSP communication protocols

Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation utilizing low-power SAR ADC technology
• Data acquisition modules interfacing with microprocessors via serial interfaces
• Battery-powered measurement devices requiring efficient power consumption management

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging type and temperature grade. Ensure that the procurement specifications align with the required operating temperature range and voltage parameters defined in the datasheet. Confirm compatibility with existing system interfaces before finalizing orders.

Selection Notes

Select this component when dual-channel simultaneous conversion at 12-bit resolution is required within a low-power constraint. Evaluate the need for the internal reference versus external precision references based on system accuracy requirements. Consider the serial interface compatibility with the host processor's available communication ports.

Part Context

This part belongs to the AD7866 series of dual-channel SAR ADCs. It shares architectural similarities with other Analog Devices data converters but is distinct in its combination of dual channels, 1 MSPS throughput, and specific power management features. It serves as a specialized solution for applications needing concurrent sampling without pipeline delays.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference pinouts, electrical specifications, and package dimensions to ensure functional equivalence. Verify that any replacement maintains the required throughput rate and resolution for the application.
