AD5761RBCPZ-RL7

Overview

The AD5761RBCPZ-RL7 is a single-channel, 16-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated low-drift 2.5 V reference with ±2 ppm/°C typical temperature coefficient and internal 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 integral nonlinearity (INL) of ±2 LSB, differential nonlinearity (DNL) of ±1 LSB, and a typical settling time of 7.5 μs for a 10 V step. It operates on analog supplies from +4.75 V to +30 V (VDD) and −16.5 V to 0 V (VSS), with a digital supply range of 1.7 V to 5.5 V.

Feature Summary

• 16-bit resolution with guaranteed monotonicity (±1 LSB max DNL) and ±2 LSB max INL.
• Integrated low-noise 2.5 V reference with ±2 ppm/°C drift and internal buffers.
• 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/CLEAR functions.

Applications

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

Procurement Notes

Verify the component matches the specific 'R' grade variant which denotes the integrated low-drift reference. Confirm the package type corresponds to the LFCSP-16 or TSSOP-16 option as indicated in the ordering guide. Ensure the operating conditions align with the specified supply voltage ranges and temperature limits.

Selection Notes

Select this model when high precision is required due to its ±2 ppm/°C reference drift and 16-bit linearity. Choose between external or internal reference modes based on noise performance needs; the internal reference offers convenience while external options may provide different noise characteristics. Verify that the desired output range fits within the supported unipolar or bipolar configurations.

Part Context

This part belongs to the AD5761R/AD5721R family, where the AD5761R is the 16-bit version and the AD5721R is the 12-bit version. Both share similar architectures but differ in resolution and accuracy grades. The 'R' suffix indicates the inclusion of the low-drift reference, distinguishing it from standard variants that may require external references for optimal performance.

Replacement Considerations

Direct substitutes within the same family include the AD5761BCPZ-RL7 (standard reference) or AD5761ACPZ-RL7 (different accuracy grade). For 12-bit applications, the AD5721R series is compatible. Ensure pinout compatibility and verify if the reference specification changes affect system calibration requirements.
