MAX5181BEEG+T

Digital To Analog Converters Overview

The MAX5181BEEG+T is a 10-bit, 40MHz current-output digital-to-analog converter (DAC) designed for signal reconstruction and arbitrary waveform generation. It operates from a single 2.7V to 3.3V supply with an internal 1.2V bandgap reference. Key electrical parameters include a full-scale output current of 1mA, integral nonlinearity of ±2 LSB, differential nonlinearity of ±1 LSB, and spurious-free dynamic range of 70dB at 2.2MHz output frequency. The device features fully differential outputs, low glitch impulse of 10pVs, and shutdown current of 1µA maximum.

Digital To Analog Converters Feature Summary

• Fully differential current-output architecture for high signal integrity
• Integrated low-noise 1.2V bandgap reference with external override capability
• Three operational modes: normal, low-power standby, and full shutdown
• Fast wake-up time from standby mode to facilitate power conservation

Digital To Analog Converters Applications

• Arbitrary Waveform Generators (AWGs)
• Direct Digital Synthesis
• Imaging Applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BEEG' corresponds to the 24-pin QSOP package and extended temperature range (-40°C to +85°C). Confirm RoHS compliance status indicated by the '+' symbol in the ordering information. Ensure the source document explicitly lists this part number as available or discontinued, as availability data may vary by region and distributor.

Digital To Analog Converters Selection Notes

Select the MAX5181BEEG+T when a 10-bit resolution and 40MHz clock speed are required for current-output applications. Choose this component over the MAX5184 if external load resistors are preferred or if driving balun transformers directly. Consider the 24-pin QSOP package constraints and separate analog/digital ground requirements for optimal performance in high-frequency designs.

Digital To Analog Converters Part Context

The MAX5181BEEG+T belongs to the MAX5181/MAX5184 family of 10-bit, 40MHz DACs manufactured by Analog Devices Inc./Maxim Integrated. This series is engineered for superior performance in applications requiring low distortion and low-power operation. The BEEG suffix specifically denotes the industrial/extended temperature grade and the 24-pin QSOP surface-mount package format.

Digital To Analog Converters Replacement Considerations

Public confirmed substitutes within the same product line include the MAX5184BEEG+, which offers identical specifications but provides on-chip precision resistors for voltage-output operation instead of current output. Both devices share the same pinout and functional characteristics, allowing for potential design flexibility depending on whether current or voltage drive is required.

Digital To Analog Converters FAQ

How does the MAX5181 handle power consumption during idle periods?

The device supports three modes: normal, low-power standby, and full shutdown. In standby mode, the reference and control amplifier remain active while the current array is inactive. In full shutdown mode, all internal circuits are disabled, reducing supply current to a maximum of 1µA.

What is the function of the REN pin regarding the internal reference?

The REN (Reference Enable) pin controls the internal 1.2V bandgap reference. Connecting REN to DGND activates the internal reference, making REFO an output. Connecting REN to DVDD disables the internal reference, allowing REFO to be used as an input for an external reference voltage.

Can the MAX5181BEEG+T operate with a single supply voltage?

Yes, the MAX5181BEEG+T is designed to operate from a single 2.7V to 3.3V supply for both analog (AVDD) and digital (DVDD) domains.
