AD7893BRZ-10REEL7

Overview

The AD7893BRZ-10REEL7 is a 12-bit successive approximation analog-to-digital converter (ADC) fabricated in LC2MOS technology. It operates from a single +5 V supply and consumes 45 mW maximum power. The device features an on-chip track/hold amplifier with a conversion time of 6 μs and a throughput rate up to 117 kHz. It accepts a bipolar analog input range of ±10 V and utilizes a two-wire serial interface for data output. The component is housed in an 8-pin SOIC package and supports an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated signal scaling circuitry enables direct interfacing with ±10 V analog signals without external attenuation components.
• On-chip track/hold amplifier ensures accurate digitization of high-frequency inputs by maintaining signal stability during the conversion cycle.
• Two-wire serial interface simplifies system integration by providing a straightforward connection to microcontrollers and DSP processors.

Applications

• Industrial process control systems requiring precise measurement of standard voltage signals
• Data acquisition modules for monitoring sensor outputs in automated machinery
• Portable instrumentation devices utilizing single-supply operation

Procurement Notes

Verify that the specific suffix 'BRZ' corresponds to the B-grade linearity variant within the 8-pin SOIC package configuration. Confirm that the REEL7 designation indicates tape-and-reel packaging suitable for automated surface-mount assembly processes. Ensure compatibility with the required ±10 V input range specification for the target application design.

Selection Notes

Select this component when a 12-bit resolution is sufficient for applications involving ±10 V input ranges. Consider the 6 μs conversion time and 117 kHz throughput rate against system timing requirements. Evaluate the single +5 V supply constraint and ensure the available board space accommodates the compact 8-pin SOIC footprint.

Part Context

This part belongs to the AD7893 family of fast, low-power ADCs. The BRZ suffix identifies the B-grade version with improved relative accuracy compared to the A-grade counterpart. The device is designed for space-constrained environments where integrating signal conditioning and conversion into a minimal pin count is essential for cost and size optimization.

Replacement Considerations

The AD7893ARZ-10REEL7 serves as a functional substitute within the same family, offering identical electrical performance but with A-grade linearity specifications instead of B-grade.
