AD7998BRUZ-1REEL

Overview

The AD7998BRUZ-1REEL is an 8-channel, 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a single-ended input architecture and operates on a 2.7 V to 5.5 V supply. The device utilizes an I2C-compatible serial interface supporting standard, fast, and high-speed modes up to 3.4 MHz. Key electrical parameters include a maximum throughput rate of 188 kSPS, a typical conversion time of 2 µs, and a signal-to-noise ratio of 71 dB. It is housed in a 20-lead TSSOP package and functions within a temperature range of −40°C to +85°C.

Feature Summary

Supports standard, fast, and high-speed I2C communication modes for flexible bus integration.
Includes an out-of-range indicator/alert function with programmable limit registers.
Features automatic shutdown between conversions to minimize power consumption.

Applications

Industrial process control systems requiring multi-channel data acquisition
Battery-powered instrumentation utilizing low-power ADC architectures
Data logging equipment with I2C-based microcontroller interfaces

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm interface mode capabilities. Ensure that the required reel packaging matches the intended automated assembly process. Confirm RoHS compliance status and lead-free soldering specifications prior to final procurement decisions.

Selection Notes

Select this component when eight single-ended channels are required alongside high-speed I2C connectivity. Compare against the AD7998-0 variant if high-speed mode support above 400 kHz is necessary. Evaluate power dissipation requirements against the specified operating current limits at the target clock frequency.

Part Context

This part belongs to the AD7997/AD7998 family of low-power, successive approximation ADCs. It serves as the 12-bit, 8-channel counterpart to the AD7997. Equivalent devices with fewer channels include the AD7992 and AD7994.
