AD7992BRMZ-0

Overview

The AD7992BRMZ-0 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. Key specifications include a signal-to-noise ratio of 71 dB, integral nonlinearity of ±1 LSB, and differential nonlinearity of -0.9 LSB/1 LSB. It functions within a temperature range of −40 °C to +125 °C and consumes a maximum of 1 µA in shutdown mode.

Feature Summary

• I2C-compatible serial interface supporting standard and fast modes
• Automatic power-down between conversions for low power efficiency
• Programmable limit registers with out-of-range alert indicator
• Pin-selectable addressing via the AS pin

Applications

• Battery-powered instrumentation systems
• Industrial process control monitoring
• Data acquisition modules requiring multi-channel input

Procurement Notes

Verify the specific ordering suffix to confirm the I2C address configuration and supported speed modes. Ensure the component matches the required package type and operating temperature range for the intended environment. Cross-reference the manufacturer's datasheet for any updates regarding RoHS compliance or material declarations before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel 12-bit ADC with I2C connectivity is required. The AD7992-0 variant specifically supports standard and fast I2C modes, distinguishing it from the AD7992-1 which adds high-speed support. Consider the external reference requirement and the available pin-selectable addresses for system bus design.

Part Context

The AD7992 belongs to Analog Devices' family of low-power, successive approximation register ADCs. This specific part number represents the version compatible with standard and fast I2C communication protocols. It shares architectural similarities with other members like the AD7994 and AD7998 but offers a distinct two-channel configuration in a compact MSOP package.

Replacement Considerations

The AD7992BRMZ-1 serves as a functional alternative that supports high-speed I2C modes in addition to standard and fast modes. Designers must verify I2C timing compatibility and address configurations when substituting between these variants.
