AD5761RARUZ

Overview

The AD5761RARUZ is a single-channel, 16-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated low-drift 2.5 V reference with ±2 ppm/°C typical drift and dual reference buffers. The device supports eight software-programmable output ranges, including unipolar (0 V to +5 V/+10 V/+16 V/+20 V) and bipolar (±3 V/±5 V/±10 V, −2.5 V to +7.5 V) configurations with 5% overrange capability. Key electrical specifications include a maximum total unadjusted error (TUE) of 0.1% FSR, guaranteed monotonicity within ±1 LSB, and a typical settling time of 7.5 μs. It operates on a digital supply of 1.7 V to 5.5 V and analog supplies up to ±16.5 V or single supply up to 30 V.

Feature Summary

• 16-bit resolution with ±2 LSB maximum INL (A Grade) and guaranteed monotonicity.
• Integrated 2.5 V reference with ±2 ppm/°C typical temperature coefficient.
• Eight programmable output ranges: 0–5 V, 0–10 V, 0–16 V, 0–20 V, ±3 V, ±5 V, ±10 V, and −2.5 V to +7.5 V.
• Asynchronous updating via LDAC and asynchronous RESET to zero/midscale.

Applications

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

Procurement Notes

Verify the package type matches the required form factor, as the AD5761R series is available in both 16-lead TSSOP and 3 mm × 3 mm LFCSP packages. Confirm that the specific suffix 'RARUZ' corresponds to the intended packaging and tape-and-reel quantity if applicable. Ensure the operating environment stays within the specified industrial temperature range of −40°C to +125°C for guaranteed performance parameters.

Selection Notes

Select this component when a high-precision, single-channel DAC with integrated reference is required. The 16-bit resolution and low glitch impulse (1 nV-sec in 0 V to 5 V range) make it suitable for sensitive applications. Consider the power supply requirements; while it supports wide analog supply ranges, ensure the digital interface voltage (DVCC) is compatible with the host microcontroller or DSP logic levels.

Part Context

The AD5761R is part of the AD5761R/AD5721R family, which also includes the 12-bit AD5721R variant. Both share identical pinouts, serial interfaces, and most functional blocks, differing primarily in resolution and accuracy grades. The AD5761R provides higher precision with A Grade INL specifications compared to the B Grade typically associated with the 12-bit version.

Replacement Considerations

The AD5721R is a direct pin-compatible alternative offering 12-bit resolution. For replacements requiring similar functionality but different packages, verify thermal impedance differences between TSSOP and LFCSP variants. No other cross-model substitutes are explicitly confirmed in the provided documentation.
