AD5721RBRUZ-RL7

Overview

The AD5721RBRUZ-RL7 is a single-channel, 12-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices. It features an internal 2.5 V reference with ±2 ppm/°C drift and operates on a single supply of +4.75 V to +30 V or dual supplies. The device supports eight software-programmable output ranges including unipolar and bipolar configurations. Key electrical specifications include a typical settling time of 7.5 μs, integral nonlinearity (INL) of ±0.5 LSB, and a signal-to-noise ratio (SNR) of 92 dB. It utilizes a 50 MHz SPI-compatible interface and is housed in a 16-lead TSSOP package.

Feature Summary

• 12-bit resolution with ±0.5 LSB INL/DNL and guaranteed monotonicity
• Internal 2.5 V reference with low drift of ±2 ppm/°C
• 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
• Fast settling time of 7.5 μs typical and low glitch impulse of 1 nV-sec

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 and packaging configuration against the manufacturer's ordering guide. Confirm that the internal reference performance meets system requirements for temperature stability and noise. Ensure the power supply rails align with the specified operating voltages for the selected output range.

Selection Notes

Select this component when a single-channel DAC with high accuracy and wide output voltage flexibility is required. The internal reference simplifies design by eliminating external precision references. Consider the 16-lead TSSOP package for surface-mount assembly. Verify compatibility with the host microcontroller's serial interface timing and voltage levels.

Part Context

This part belongs to the AD5761R/AD5721R family, which offers 16-bit and 12-bit resolutions respectively. The AD5721R variant provides 12-bit performance with tighter linearity specifications compared to lower-grade options. It shares the same pinout and functional architecture as the 16-bit AD5761R, allowing for potential design scalability within the same package footprint.
