AD5311BRMZ-REEL7

Digital To Analog Converters Overview

The AD5311BRMZ-REEL7 is a single-channel, 10-bit buffered voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from a single 2.5 V to 5.5 V supply with a typical current consumption of 120 μA at 3 V. The device features an on-chip rail-to-rail output buffer amplifier and utilizes a 2-wire I²C-compatible serial interface supporting clock rates up to 400 kHz. Key specifications include a settling time of 9 μs (typical), power-on reset to 0 V, and three software-selectable power-down modes reducing current to 50 nA. It is housed in an 8-lead MSOP package.

Digital To Analog Converters Feature Summary

• 10-bit resolution with guaranteed monotonicity over all codes
• 2-wire (I²C-compatible) serial interface with data readback capability
• On-chip rail-to-rail output buffer amplifier with 0.7 V/μs slew rate
• Power-on reset ensures DAC output powers up to 0 V

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment
• Programmable voltage and current sources
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the B version industrial temperature range (-40°C to +105°C) and confirm the 8-lead MSOP package configuration. Ensure the design supports the required I²C bus addressing via A0 and A1 pins for multiple device integration.

Digital To Analog Converters Selection Notes

Select this component for applications requiring low power consumption and a buffered voltage output. The reference is derived from the power supply, providing the widest dynamic output range without an external reference. Consider the 10-bit resolution and 9 μs settling time for speed requirements.

Digital To Analog Converters Part Context

This part belongs to the AD5301/AD5311/AD5321 family of micropower DACs. The AD5311 specifically provides 10-bit resolution, distinguishing it from the 8-bit AD5301 and 12-bit AD5321 variants within the same series.

Digital To Analog Converters FAQ

How is the DAC reference voltage determined?

The reference for the DAC is derived directly from the power supply inputs (VDD), which allows for the widest dynamic output range.

What is the maximum SCL clock frequency?

The 2-wire serial interface supports clock rates up to 400 kHz.

Does the device support data readback?

Yes, the AD5311 supports reading back one or two bytes of data (data and power-down mode bits) via the SDA line during a read cycle.
