AD5761RACPZ-RL7

Overview

The AD5761RACPZ-RL7 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 supply operation ranging from +4.75 V to +30 V or −16.5 V to 0 V. The device offers eight software-programmable output ranges including unipolar and bipolar options, with a maximum total unadjusted error of 0.1% FSR. Key performance metrics include ±2 LSB maximum INL, guaranteed monotonicity, 7.5 μs typical settling time, and 35 nV/√Hz noise. It operates within an industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify the package type corresponds to the LFCSP variant indicated by the 'ACPZ' suffix in the part number. Confirm the reel packaging designation 'RL7' matches the required quantity for production needs. Ensure the operating environment stays within the specified −40°C to +125°C industrial temperature range for guaranteed specifications.

Selection Notes

Select this component when a high-precision 16-bit DAC is required with integrated reference capabilities. The AD5761R provides superior linearity compared to the 12-bit AD5721R. Consider the available output ranges and supply voltage requirements (+4.75 V to +30 V) during system design. The asynchronous LDAC and RESET functions offer flexibility in updating outputs without disrupting other system operations.

Part Context

This part belongs to the AD5761R/AD5721R family of multiple range, 16-/12-bit bipolar/unipolar voltage output DACs. The AD5761R specifically denotes the 16-bit resolution variant, while the AD5721R is the 12-bit version. Both share similar architectures, interfaces, and feature sets, differing primarily in resolution and associated accuracy specifications.

Replacement Considerations

The AD5721R serves as a lower-resolution alternative within the same family. Verify pin compatibility and software register configurations when substituting between the 16-bit AD5761R and 12-bit AD5721R variants.

FAQ

What is the maximum clock speed for the serial interface?

The serial interface supports clock rates up to 50 MHz in write mode and up to 33 MHz in readback mode.

How does the asynchronous RESET function operate?

Asserting the active-low RESET pin returns the device to its default power-on status, clamping the output to ground and powering down the output buffer.

What is the purpose of the ALERT pin?

The ALERT pin is asserted low when the die temperature exceeds approximately 150°C, or if an output short circuit or brownout condition occurs.
