AD5311BRMZ-REEL

Digital To Analog Converters Overview

The AD5311BRMZ-REEL is a single-channel, 10-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply with typical current consumption of 120 μA at 3 V. The device features an I²C-compatible 2-wire serial interface supporting clock rates up to 400 kHz and includes data readback capability. Key specifications include a settling time of 9 μs, rail-to-rail output swing, and guaranteed monotonicity by design. It incorporates power-on reset to 0 V and three software-selectable power-down modes reducing current to 50 nA at 3 V.

Digital To Analog Converters Feature Summary

• 10-bit resolution with resistor-string architecture
• I²C-compatible 2-wire serial interface with data readback
• Rail-to-rail output buffer amplifier with 0.7 V/μs slew rate
• Micropower operation: 120 μA at 3 V; 50 nA in power-down mode

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 REEL suffix indicates tape-and-reel packaging for automated assembly. Confirm the B version industrial temperature range (-40°C to +105°C) matches application requirements. Ensure the MSOP-8 package footprint aligns with PCB layout constraints. Validate that the external pull-up resistors on SCL and SDA lines are appropriate for the system voltage levels.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 10-bit DAC with low power consumption is required. The integrated reference derived from VDD simplifies design compared to external reference parts. Consider the 9 μs settling time and 0.7 V/μs slew rate for dynamic signal applications. The I²C interface allows multiple devices on one bus using A0 and A1 address pins.

Digital To Analog Converters Part Context

This part belongs to the AD5301/AD5311/AD5321 family of nanoDACs. The AD5311 specifically provides 10-bit resolution, distinguishing it from the 8-bit AD5301 and 12-bit AD5321. All variants share similar pinouts, interfaces, and power characteristics, differing primarily in resolution and linearity specifications.
