AD7992BRMZ-1

Overview

The AD7992BRMZ-1 is a 12-bit successive approximation analog-to-digital converter featuring an I2C-compatible serial interface. It integrates two single-ended analog input channels and operates from a single power supply ranging from 2.7 V to 5.5 V. The device supports throughput rates up to 188 kSPS with a typical conversion time of 2 µs. It includes internal limit registers for out-of-range detection via an ALERT output, automatic shutdown mode consuming 1 µA maximum, and pin-selectable addressing to allow multiple devices on the same bus.

Feature Summary

• I2C-compatible serial interface supporting standard, fast, and high-speed modes
• Automatic power-down between conversions to minimize energy usage
• Configurable out-of-range indicator alert function
• Pin-selectable addressing for flexible multi-device bus configurations

Applications

• Battery-powered instrumentation systems requiring low current consumption
• Industrial process control monitoring with single-ended signals
• Data acquisition modules utilizing I2C communication protocols
• Portable measurement devices operating on limited voltage supplies

Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm interface speed capabilities. Ensure the ordering part number matches the required I2C mode specifications for the target application design.

Selection Notes

Select this component when dual-channel 12-bit resolution is required alongside strict power constraints. Confirm that the external reference voltage range aligns with the available supply rails and that the I2C bus timing meets the system clock requirements.

Part Context

This device belongs to the AD7992 series of low-power ADCs. It shares architectural similarities with other members like the AD7994 but offers fewer input channels. The BRMZ variant indicates a specific temperature range and package configuration within the Analog Devices portfolio.

Replacement Considerations

Direct substitutes include the AD7992-0 for applications not requiring high-speed I2C modes. Other family members such as the AD7994 provide additional channels but may require different pinout considerations.
