AD5761RBRUZ-RL7

Overview

The AD5761RBRUZ-RL7 is a single-channel, 16-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices. It operates from single supply voltages of +4.75 V to +30 V or dual supplies ranging from −16.5 V to 0 V for VSS and +4.75 V to +16.5 V for VDD. The device integrates an output amplifier, reference buffer, and a low-drift 2.5 V reference with ±2 ppm/°C typical drift. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB, guaranteed monotonicity with ±1 LSB differential nonlinearity (DNL), and a typical settling time of 7.5 μs. It features a DSP-compatible serial interface operating up to 50 MHz and supports eight software-programmable output ranges.

Feature Summary

• 16-bit resolution with ±2 LSB maximum INL and guaranteed monotonicity
• Integrated low-drift 2.5 V reference (±2 ppm/°C typical)
• Eight software-programmable output ranges including unipolar and bipolar options
• Serial interface compatible with DSP/microcontrollers, supporting up to 50 MHz clock rates

Applications

• Industrial automation systems
• Instrumentation and data acquisition
• Open-/closed-loop servo control
• Process control applications
• Programmable logic controllers

Procurement Notes

Verify the package type matches the required design; the BRUZ suffix indicates a 16-lead TSSOP package. Confirm the RL7 suffix corresponds to the reel packaging format specified in the ordering guide. Ensure the B grade selection meets the ±2 LSB INL requirement for the target application ranges.

Selection Notes

Select this component when a high-precision 16-bit DAC with integrated reference is required. The AD5761R provides superior temperature stability compared to the AD5761 due to its ±2 ppm/°C reference. Consider the power supply requirements, as bipolar ranges necessitate a negative supply rail down to −16.5 V.

Part Context

This part belongs to the AD5761R/AD5721R family of multiple range, 16-/12-bit, bipolar/unipolar voltage output DACs. The AD5761R variant specifically offers 16-bit resolution and an integrated precision reference, distinguishing it from the 12-bit AD5721R and the standard AD5761 which lacks the low-drift internal reference.

Replacement Considerations

The AD5761RBRUZ is a direct pin-compatible alternative to the AD5761BRUZ, offering improved reference drift characteristics. For 12-bit applications, the AD5721R series serves as a lower-resolution substitute within the same package footprint.
