AD7993BRUZ-0REEL

Overview

The AD7993BRUZ-0REEL is a 4-channel, 10-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an I2C-compatible serial interface and operates from a single 2.7 V to 5.5 V power supply. The device provides a throughput rate of up to 188 kSPS with a typical conversion time of 2 µs. It includes a track-and-hold amplifier capable of handling input frequencies up to 11 MHz. Key specifications include ±0.5 LSB maximum integral and differential nonlinearity, ±1.5 LSB gain error, and a shutdown current of 1 µA maximum. The component is housed in a 16-lead TSSOP package and supports standard, fast, and high-speed I2C modes.

Feature Summary

• I2C-compatible serial interface with pin-selectable addressing for multi-device bus configurations
• Automatic cycle interval mode and one-shot conversion control via CONVST pin
• Programmable out-of-range indicator/alert function with open-drain output
• Low power consumption with automatic shutdown between conversions

Applications

• Battery-powered portable instrumentation
• Industrial process control systems
• Data acquisition modules
• Environmental monitoring sensors

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm interface mode compatibility. Ensure the reel packaging matches production requirements. Confirm RoHS compliance status through the latest datasheet revision. Validate that the AS pin configuration aligns with the intended I2C address selection for the target application design.

Selection Notes

Select this model when four single-ended analog inputs are required within a low-power constraint. The AD7993 variant is appropriate for applications needing 10-bit resolution. Verify that the system I2C clock frequency does not exceed the specified limits for the -0 suffix version. Consider the external reference voltage range requirements relative to the available supply rails.

Part Context

This component belongs to the AD7993/AD7994 family of low-power ADCs. The AD7993 specifically denotes the 10-bit resolution version, while the AD7994 offers 12-bit resolution. Both share identical pinouts and functional blocks, differing primarily in accuracy specifications. The BRUZ suffix indicates the industrial temperature range and surface mount TSSOP packaging.

Replacement Considerations

The AD7994BRUZ-0REEL serves as a direct pin-compatible alternative offering higher 12-bit resolution. For applications requiring fewer channels, the AD7992 series provides equivalent functionality with reduced channel counts.
