AD7992BRMZ-0REEL

Overview

The AD7992BRMZ-0REEL is a 12-bit successive approximation analog-to-digital converter (ADC) 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 registers for limit monitoring, an out-of-range alert function, and automatic shutdown modes that reduce current consumption to 1 µA maximum. The component is housed in a compact 10-lead MSOP package.

Feature Summary

• I2C-compatible serial interface supporting standard and fast modes
• Automatic power-down mode between conversions for low power efficiency
• Configurable out-of-range indicator/alert output function
• Pin-selectable addressing via the AS pin for bus configuration

Applications

• Battery-powered instrumentation systems requiring low power consumption
• Industrial process control loops utilizing I2C communication
• Data acquisition modules with multiple sensor inputs
• Portable medical devices and handheld test equipment

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm interface speed capabilities and packaging type. Ensure the selected variant matches the required I2C clock frequency specifications for the target application environment. Cross-reference the datasheet revision to validate performance parameters under operating conditions.

Selection Notes

Select this component when a 12-bit resolution is required alongside minimal board space constraints provided by the MSOP package. Consider the AD7992-1 variant if high-speed I2C modes exceeding 400 kHz are necessary. Evaluate the external reference voltage requirements, as the device supports references up to the supply voltage.

Part Context

This part belongs to the AD7992 family of low-power ADCs manufactured by Analog Devices Inc. The series offers various channel counts and packages, including 4-channel and 8-channel options. The BRMZ designation indicates the commercial temperature range extension and surface-mount packaging format suitable for automated assembly processes.

Replacement Considerations

Direct functional substitutes within the same family include the AD7992BRMZ-1REEL, which supports high-speed I2C modes. Other related products listed in the datasheet include the AD7994 and AD7998 for applications requiring additional input channels.
