AD7993BRU-0

Overview

The AD7993BRU-0 is a 4-channel, 10-bit successive approximation analog-to-digital converter (ADC) featuring an I2C-compatible serial interface. It operates from a single 2.7 V to 5.5 V supply and achieves a throughput rate of up to 188 kSPS with a typical conversion time of 2 µs. The device includes four single-ended analog input channels, an external reference input range of 1.2 V to VDD, and supports standard and fast I2C modes. It is housed in a 16-lead TSSOP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Four single-ended analog input channels with integrated track-and-hold amplifier
• I2C-compatible serial interface supporting standard and fast modes
• Automatic shutdown mode for low power consumption when not converting
• Out-of-range indicator/alert function via ALERT/BUSY pin

Applications

• Battery-powered instruments requiring low power consumption
• Industrial process control systems
• Data acquisition systems with multiple sensor inputs

Procurement Notes

Verify the specific suffix '0' indicates support for standard and fast I2C modes only, excluding high-speed mode. Confirm the B version designation corresponds to the extended industrial temperature range of -40°C to +125°C. Ensure the TSSOP-16 package matches the target PCB footprint requirements.

Selection Notes

Select this component for applications requiring four single-ended inputs with moderate resolution. Compare against the AD7994 if 12-bit resolution is necessary. Consider the AD7998 or AD7992 if eight or two channels are required respectively. Verify that the system clock frequency does not exceed 400 kHz for the AD7993-0 variant.

Part Context

This part belongs to the AD7993/AD7994 family of low-power, multi-channel ADCs. It shares architectural similarities with the AD7998 (8-channel) and AD7992 (2-channel) devices. The '-0' suffix distinguishes it from the '-1' variant by limiting I2C speed capabilities while maintaining identical pinout and core functionality.

Replacement Considerations

The AD7993BRUZ-0 is the lead-free RoHS-compliant equivalent of the AD7993BRU-0. Both share identical electrical specifications and pin configurations.
