AD5761ARUZ-RL7

Overview

The AD5761ARUZ-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 features an integrated output amplifier and reference buffer, supporting eight software-programmable output ranges including unipolar and bipolar spans up to ±10 V with 5% overrange capability. Key electrical specifications include a maximum integral nonlinearity (INL) of ±8 LSB, guaranteed monotonicity within ±1 LSB, and a typical settling time of 7.5 μs on selected ranges.

Feature Summary

• 16-bit resolution with ±8 LSB maximum INL and ±1 LSB maximum DNL
• Eight software-programmable output ranges: 0 V to +5 V, 0 V to +10 V, 0 V to +16 V, 0 V to +20 V, ±3 V, ±5 V, ±10 V, and −2.5 V to +7.5 V
• Serial interface compatible with DSP and microcontrollers, operating at clock rates up to 50 MHz
• Integrated reference buffers and asynchronous updating via LDAC

Applications

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

Procurement Notes

Verify the specific grade A performance parameters against the datasheet Table 2, as the AD5761R variant includes an internal reference which differs from this external reference model. Confirm that the TSSOP-16 package and reel packaging align with assembly requirements. Ensure power supply decoupling meets the specified headroom requirements for the chosen output range.

Selection Notes

Select the AD5761ARUZ-RL7 when a 16-bit resolution with external reference configuration is required. This part is suitable for applications needing wide supply voltage flexibility and multiple programmable output spans. Compare against the AD5761R if an integrated low-drift reference is preferred, or the AD5721 if 12-bit resolution suffices for the application.

Part Context

The AD5761/AD5721 series provides precision voltage output DACs in 16-lead TSSOP and LFCSP packages. The AD5761 offers 16-bit resolution while the AD5721 provides 12-bit resolution. Both share pin compatibility and functional similarities, differing primarily in resolution and associated accuracy grades. The 'A' suffix denotes Grade A performance specifications.

Replacement Considerations

The AD5761RBRUZ is a pin-compatible alternative featuring an integrated 2 ppm/°C reference. For lower resolution needs, the AD5721 series serves as a direct substitute. Verify that any replacement maintains the required serial interface timing and output drive capabilities.
