AD7993BRUZ-1

Overview

The AD7993BRUZ-1 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 supporting standard, fast, and high-speed modes with a maximum throughput rate of 188 kSPS. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and includes a track-and-hold amplifier capable of handling input frequencies up to 11 MHz. Key specifications include a typical conversion time of 2 µs, integral nonlinearity (INL) of ±0.5 LSB max, differential nonlinearity (DNL) of ±0.5 LSB max, and offset error of ±1.5 LSB max in Mode 1. It is housed in a 16-lead TSSOP package and supports an operating temperature range of −40°C to +125°C.

Feature Summary

• I2C-compatible serial interface with pin-selectable addressing for multiple devices on the same bus
• Sequencer operation with automatic cycle interval mode and one-shot conversion rates
• Out-of-range indicator/alert function with programmable high and low limit registers
• Low power consumption with automatic shutdown during non-converting periods

Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable battery-powered instrumentation due to low power characteristics
• Automotive sensor interfaces operating within extended temperature ranges
• Data loggers utilizing I2C communication protocols

Procurement Notes

Verify the specific suffix '-1' indicates support for I2C high-speed mode compared to the '-0' variant. Confirm the B version designation corresponds to the industrial temperature range of -40°C to +125°C. Ensure the TSSOP-16 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when four single-ended channels are required with I2C connectivity. Choose the BRUZ-1 variant over BRUZ-0 if system clock speeds exceed 400 kHz. Consider the external reference requirement as the device does not include an internal voltage reference. Evaluate power dissipation limits against the thermal constraints of the application environment.

Part Context

This part belongs to the AD7993/AD7994 family of low-power, 4-channel ADCs. It serves as the 10-bit resolution counterpart to the 12-bit AD7994. The series is designed for applications needing moderate resolution with flexible I2C integration. Related devices in the product line include the 8-channel AD7998 and the 2-channel AD7992.

Replacement Considerations

The AD7993BRUZ-0 is a compatible alternative that supports only standard and fast I2C modes. The AD7994BRUZ-1 offers higher 12-bit resolution but maintains similar interface and power characteristics.
