MAX5180BEEI+

Digital To Analog Converters Overview

The MAX5180BEEI+ is a dual, 10-bit digital-to-analog converter featuring simultaneous output updates and current-mode operation. It operates from a single 2.7V to 3.3V supply with a maximum clock frequency of 40MHz. The device delivers a full-scale output current of 1mA into 400Ω differential loads, achieving a settling time of 25ns. Key performance metrics include a spurious-free dynamic range of 70dB at 2.2MHz output, a glitch impulse of 10pVs, and integral/differential nonlinearity of ±0.5 LSB. It incorporates an internal 1.2V bandgap reference and supports shutdown currents as low as 1µA.

Digital To Analog Converters Procurement Notes

Verify the specific suffix BEEI+ corresponds to the 28-pin QSOP package and extended temperature range (-40°C to +85°C). Confirm that the component is the current-output variant (MAX5180), distinct from the voltage-output MAX5183 which includes internal resistors. Ensure compatibility with 2.7V to 3.3V logic levels for digital inputs.

Digital To Analog Converters Selection Notes

Select this component when simultaneous dual-channel conversion is required for high-speed applications. The MAX5180 provides current outputs suitable for driving baluns or external amplifiers, whereas the MAX5183 offers integrated voltage outputs. Consider the 40MHz clock speed and 25ns settling time for bandwidth requirements. Evaluate the need for the internal reference versus an external precision source based on system noise sensitivity.

Digital To Analog Converters Part Context

This device belongs to the Maxim Integrated MAX518x family of high-speed DACs. It shares architectural similarities with the MAX5183 but differs in output configuration. Lower-resolution alternatives in the series include the 8-bit MAX5186 and MAX5189. The MAX5180 is specifically engineered for communications systems demanding superior dynamic performance and low power consumption.

Digital To Analog Converters Replacement Considerations

Public documentation confirms the MAX5183BEEI+ as a functional substitute within the same package and temperature range, provided the application can accommodate voltage outputs rather than current outputs. No other direct pin-compatible replacements are explicitly verified in the provided datasheet.

Digital To Analog Converters FAQ

How does the MAX5180 handle power-down states?

The device offers three modes: normal operation, standby mode where the reference and amplifier remain active while the array is inactive, and shutdown mode which reduces supply current to 1µA by disabling all internal blocks.

What is the function of the REN pin?

The REN pin is an active-low reference enable. Connecting it to AGND activates the internal 1.2V bandgap reference, while connecting it to AVDD disables the internal reference to allow an external voltage source to drive the REFO pin.

How is the full-scale output current determined?

For the MAX5180, the full-scale output current (IFS) is set by an external resistor RSET connected between AVDD and REFR, calculated as IFS = 8 × IREF, where IREF is derived from the internal 1.2V reference divided by RSET.
