AD7863ARSZ-10REEL7

Overview

The AD7863ARSZ-10REEL7 is a dual 14-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5 V supply and features two simultaneous sampling channels with four input pins. The device utilizes a successive approximation architecture and provides a high-speed parallel interface for data transfer. Key electrical parameters include a maximum conversion time of 5.2 μs, a typical power consumption of 70 mW in normal mode, and an input voltage range of ±10 V. The component supports an operating temperature range from -40°C to +85°C and is housed in a 28-lead SOIC_W package.

Feature Summary

• Simultaneous sampling and conversion on two independent channels
• Integrated internal 2.5 V reference voltage source
• High-speed parallel data interface compatible with standard logic
• Automatic power-down mode for reduced energy consumption

Applications

• Vector motor control systems requiring phase information preservation
• Industrial process monitoring with standard ±10 V signal inputs
• Portable instrumentation utilizing low-power operation modes

Procurement Notes

Verify the specific suffix configuration against official documentation to confirm the ±10 V input range specification. Ensure that the reel packaging format aligns with automated assembly requirements. Cross-reference the manufacturing date code and RoHS compliance status with current distributor declarations prior to final procurement authorization.

Selection Notes

Select this component when simultaneous channel sampling is required to maintain relative phase accuracy between signals. The ±10 V input range makes it suitable for direct connection to standard industrial sensors without external attenuation. Consider the parallel interface requirements and available microprocessor bus width during system design integration.

Part Context

This part belongs to the AD7863 family of dual ADCs, serving as a 14-bit upgrade to the AD7862 series. The '10' designation indicates the specific ±10 V input range variant. The 'REEL7' suffix denotes tape and reel packaging for surface mount technology applications.

Replacement Considerations

The AD7862 is a compatible predecessor offering similar functionality with potentially different pinout or performance characteristics. Verify interface compatibility and thermal specifications when substituting.
