AD7997BRUZ-1REEL

Overview

The AD7997BRUZ-1REEL is an 8-channel, 10-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a 2 µs typical conversion time and supports throughput rates up to 188 kSPS. The device operates from a single 2.7 V to 5.5 V power supply and includes an I2C-compatible serial interface supporting standard, fast, and high-speed modes. It utilizes a 20-lead TSSOP package and functions within a temperature range of −40°C to +85°C.

Feature Summary

• Integrates an 8-channel multiplexer with track-and-hold amplifier for single-ended inputs.
• Supports pin-selectable I2C addressing to allow multiple devices on the same bus.
• Includes programmable limit registers with an open-drain out-of-range alert output.

Applications

• Battery-powered data acquisition systems
• Industrial process control monitoring
• Portable instrumentation

Procurement Notes

Verify that the ordering suffix matches the required I2C speed mode and packaging format. Confirm the specific revision level against the manufacturer's current documentation to ensure compatibility with system design requirements.

Selection Notes

Select this component when an 8-channel ADC with I2C connectivity is required. Ensure the application supports the specified voltage range and thermal conditions. Verify that the external reference voltage meets the minimum requirement for the desired dynamic performance.

Part Context

This part belongs to the AD7997/AD7998 family of low-power, multi-channel ADCs. It shares architectural similarities with the AD7992 and AD7994 but provides eight input channels instead of two or four. The BRU designation indicates the commercial temperature grade and surface-mount package type.

Replacement Considerations

Direct equivalents include the AD7997BRUZ-0REEL for standard and fast I2C modes only. Other family members like the AD7998 offer 12-bit resolution with similar pinouts and functionality.
