AD7863BRZ-10

Overview

The AD7863BRZ-10 is a dual 14-bit successive approximation analog-to-digital converter (ADC) operating from a single 5 V supply. It features two simultaneous sampling channels with four input terminals, achieving a throughput rate of 175 kSPS and a conversion time of 5.2 μs. The device includes an internal 2.5 V reference and supports a ±10 V analog input range. Key electrical specifications include a typical signal-to-noise ratio of 78 dB, a maximum differential nonlinearity of ±1 LSB, and a power consumption of 70 mW in normal mode.

Feature Summary

• Simultaneous sampling and conversion across two independent channels to preserve relative phase information.
• Integrated high-speed parallel interface compatible with standard microprocessor control signals.
• Automatic power-down mode that minimizes energy consumption between conversion cycles.

Applications

• Vector motor control systems requiring precise phase data.
• Portable instrumentation utilizing battery power.
• Industrial data acquisition systems interfacing with DSPs.

Procurement Notes

Verify the specific suffix 'B' indicates the industrial temperature grade (-40°C to +85°C). Confirm the '-10' designation matches the required ±10 V input voltage range for your application. Ensure the package type corresponds to the SOIC_W or SSOP variant specified in the final ordering guide.

Selection Notes

Select this component when simultaneous multi-channel sampling is critical for maintaining signal phase relationships. The B version provides extended temperature coverage compared to commercial variants. Consider the 14-bit resolution and 175 kSPS speed against system bandwidth requirements before implementation.

Part Context

This part belongs to the AD7863 family, which serves as a 14-bit upgrade to the 12-bit AD7862 series. The BRZ-10 variant specifically denotes the industrial temperature range, lead-free RoHS-compliant packaging, and the ±10 V input scaling configuration within the broader product line.

Replacement Considerations

The AD7862 series offers 12-bit resolution but lacks simultaneous sampling capabilities. Verify pin compatibility if substituting older designs, noting that the AD7863 maintains lead compatibility while providing enhanced dynamic performance and dual-channel architecture.
