AD7992BRMZ-1-R2

Overview

The AD7992BRMZ-1-R2 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 2.7 V to 5.5 V supply. 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, pin-selectable addressing, and automatic shutdown mode consuming 1 µA maximum current. The component is housed in a 10-lead MSOP package and functions within a temperature range of −40 °C to +125 °C.

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 with programmable high and low limits
• Pin-selectable addressing allowing multiple devices on the same bus

Applications

• Portable battery-powered instrumentation systems
• Industrial process control monitoring
• Data acquisition modules requiring multi-channel input
• Automotive sensor signal conditioning

Procurement Notes

Verify the specific suffix -R2 against manufacturer documentation to confirm reel packaging specifications. Ensure the B version designation matches the required industrial temperature range. Confirm that the -1 variant supports the necessary high-speed I2C clock frequencies for the target application design.

Selection Notes

Select this component when dual-channel 12-bit resolution is required alongside low power consumption. The -1 suffix indicates support for high-speed I2C modes up to 3.4 MHz. Verify that the external reference voltage falls within the 1.2 V to VDD range. Consider the MSOP package dimensions for PCB layout constraints.

Part Context

This part belongs to the AD7992 family of low-power ADCs. It shares architectural similarities with the AD7994 and AD7998 but offers fewer channels. The -1 suffix distinguishes it from the AD7992-0 by enabling high-speed I2C operation. It serves as a compact solution for applications needing moderate speed and resolution.

Replacement Considerations

AD7992BRMZ-0: Supports only standard and fast I2C modes without high-speed capability.
