AD7993BRU-0REEL

Overview

The AD7993BRU-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 on a single power supply ranging from 2.7 V to 5.5 V. The device provides a throughput rate of up to 188 kSPS with a typical conversion time of 2 µs. It includes four single-ended analog input channels, an external reference input, and supports standard, fast, and high-speed I2C modes. The component is housed in a 16-lead TSSOP package and is rated for operation between -40°C and +125°C.

Feature Summary

• Four single-ended analog input channels with integrated track-and-hold amplifier
• I2C-compatible serial interface supporting standard, fast, and high-speed modes
• Automatic shutdown mode reducing current consumption to 1 µA maximum when inactive
• Configurable out-of-range indicator/alert function via software

Applications

• Battery-powered instruments requiring low power consumption
• High-speed closed-loop control systems
• Portable data acquisition applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm pin-selectable addressing capabilities and supported I2C speed modes. Ensure the reel packaging matches the required quantity specifications for the intended production volume. Cross-reference the B version temperature range requirements with the application environment.

Selection Notes

Select this component for designs requiring a 10-bit resolution with four single-ended inputs and I2C connectivity. Consider the AD7994 variant if 12-bit resolution is necessary. Verify that the system bus supports the required I2C clock frequencies for the desired throughput rate. Ensure the external reference voltage falls within the specified 1.2 V to VDD range.

Part Context

This part belongs to the AD7993/AD7994 family of low-power, multi-channel ADCs. It shares architectural similarities with the AD7998 and AD7992 devices, which offer eight and two channels respectively. The BRU-0REEL designation indicates a specific tape and reel packaging configuration for automated assembly processes.

Replacement Considerations

The AD7994BRU-0REEL serves as a higher-resolution alternative within the same package. For different channel counts, consider the AD7998 or AD7992 equivalents.
