AD7863BR-3REEL7

Overview

The AD7863BR-3REEL7 is a dual 14-bit successive approximation analog-to-digital converter (ADC) from Analog Devices. It features two simultaneous sampling channels with a throughput rate of 175 kSPS and a conversion time of 5.2 μs. The device operates on a single 5 V supply, consuming 70 mW typical power in normal mode and 105 μW maximum in power-down mode. It includes an internal 2.5 V reference and supports ±2.5 V input ranges. The part utilizes a high-speed parallel interface and is housed in a 28-lead SOIC_W package.

Feature Summary

• Simultaneous sampling and conversion for two independent channels
• Internal 2.5 V precision voltage reference
• High-speed parallel data interface compatible with standard logic
• Automatic power-down mode to minimize energy consumption

Applications

• Vector motor control systems
• Industrial process control monitoring
• Data acquisition systems requiring phase preservation

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing this component. Confirm that the BR version meets the required temperature range specifications for your application environment. Ensure compatibility with the ±2.5 V input range variant before finalizing procurement orders.

Selection Notes

Select the AD7863BR-3REEL7 when simultaneous channel sampling is critical for maintaining signal phase relationships. This model is appropriate for applications requiring a ±2.5 V input range rather than the wider ±10 V or unipolar options. Consider the parallel interface requirements and available PCB space for the 28-lead package during system design.

Part Context

This component belongs to the AD7863 family of dual ADCs, serving as a 14-bit upgrade path to the older AD7862 series. The AD7863 provides enhanced dynamic performance while maintaining similar form factors. The B version denotes industrial temperature grade operation, distinguishing it from commercial variants.

Replacement Considerations

The AD7863ARZ-3 is a lead-compatible alternative within the same family offering identical electrical characteristics in tube packaging.
