AD7892BRZ-3

Analog To Digital Converters (ADC) Overview

The AD7892BRZ-3 is a 12-bit successive approximation analog-to-digital converter (ADC) fabricated in Analog Devices' LC2MOS process. It operates from a single +5 V supply and achieves a throughput rate of 600 kSPS with a conversion time of 1.47 µs. The device features an internal +2.5 V reference, a track/hold amplifier, and flexible serial or parallel interfaces. It accepts a ±2.5 V analog input range and includes overvoltage protection up to ±7 V on the analog inputs. Typical power consumption is 60 mW in normal operation.

Analog To Digital Converters (ADC) Feature Summary

• Integrated signal scaling allows direct handling of ±2.5 V input signals while operating from a single +5 V supply.
• Flexible interface architecture supports both high-speed parallel connections and three-wire serial communication for microprocessors and DSPs.
• On-chip track/hold amplifier ensures accurate acquisition of full-scale sine waves at maximum sampling rates.
• Built-in overvoltage protection safeguards analog input ports against transient voltages exceeding the specified range.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Industrial data acquisition modules
• Digital signal processing front-ends

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BRZ-3' corresponds to the required temperature range, accuracy class, and packaging format. Confirm that the ±2.5 V input range matches the application requirements. Ensure compatibility with the intended serial or parallel bus timing specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 600 kSPS speed are required within a single-supply environment. Consider the AD7892BRZ-3 specifically for applications needing a ±2.5 V input range with overvoltage tolerance. Evaluate the trade-off between parallel and serial interface modes based on available microprocessor resources.

Analog To Digital Converters (ADC) Part Context
