MAX5181BEEG+

Digital To Analog Converters Overview

The MAX5181BEEG+ is a 10-bit, 40MHz digital-to-analog converter in a 24-pin QSOP package. It operates from a single 2.7V to 3.3V supply with a typical digital current of 5.0mA and analog current of 4.0mA at 3V. The device features a glitch impulse of 10pVs and an output settling time of 25ns to ±0.5LSB. Integral nonlinearity is typically ±0.5LSB, while differential nonlinearity is guaranteed monotonic within ±1LSB. Spurious-free dynamic range reaches 70dBc at 2.2MHz output frequency.

Digital To Analog Converters Feature Summary

• Integrated 1.2V low-noise bandgap reference with external override capability
• Three power modes including shutdown with 1µA maximum current consumption
• Fast wake-up time of 0.5µs from standby mode to full operation

Digital To Analog Converters Applications

• Signal reconstruction in communication systems
• Arbitrary waveform generators (AWGs)
• Direct digital synthesis (DDS) circuits
• Imaging applications requiring high-speed conversion

Digital To Analog Converters Procurement Notes

Verify the specific suffix BEEG corresponds to the 24-pin QSOP package and extended temperature range when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure pinout compatibility with existing board layouts, particularly regarding the separate analog and digital ground connections.

Digital To Analog Converters Selection Notes

Select the MAX5181BEEG+ for applications requiring fully differential current outputs and high-speed clocking up to 40MHz. Choose this component over voltage-output variants when external load resistors are preferred or when driving balun transformers. Consider the integrated reference for simplified designs, or utilize the external reference input for tighter drift specifications.

Digital To Analog Converters Part Context

This part belongs to the MAX518x family of high-speed DACs designed for superior performance in signal reconstruction. The MAX5181 provides current output, while the MAX5184 offers voltage output with on-chip precision resistors. Both share identical electrical specifications and are optimized for low-power operation in portable and battery-driven equipment.

Digital To Analog Converters Replacement Considerations

The MAX5184BEEG+ serves as a direct functional substitute if voltage output is required instead of current output, sharing the same package and pinout. Other members of the MAX518x family may offer different resolutions or packaging options but require verification of timing and electrical parameter compatibility.

Digital To Analog Converters FAQ

How is the full-scale output current determined for the MAX5181?

The full-scale output current is set by the internal control amplifier and the reference resistor connected between REFR and AGND. The relationship is defined as IFS = 8 * IREF.

What is the difference in operation between the MAX5181 and MAX5184?

The MAX5181 provides a fully differential current output, whereas the MAX5184 includes on-chip precision resistors to convert the current array into a differential voltage output.

Can the internal reference be disabled?

Yes, connecting the REN pin to DVDD disables the internal 1.2V bandgap reference, allowing an external reference voltage to be applied to the REFO pin.
