MAX5154BEEE

Digital To Analog Converters Overview

The MAX5154BEEE+ is a low-power, dual, 12-bit voltage-output digital-to-analog converter (DAC) in a 16-pin QSOP package. It features an internal gain of +2V/V and rail-to-rail output swing. The device operates from a single +5V supply with typical quiescent current of 500µA and 2µA in shutdown mode. It supports SPI/QSPI and Microwire serial interfaces with double-buffered input registers. Key electrical parameters include a 15µs settling time, ±1 LSB INL/DNL accuracy, and independent reference inputs for each channel.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with integrated +2V/V gain amplifiers
• Rail-to-rail output capability maximizing dynamic range
• Software-programmable shutdown mode for ultra-low power consumption
• Flexible serial interface compatible with standard microprocessor protocols

Digital To Analog Converters Applications

• Industrial process control systems
• Remote industrial controls and monitoring
• Motion control applications requiring precise analog adjustment
• Automatic test equipment (ATE) for signal generation
• Microprocessor-controlled systems needing digital offset and gain adjustment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BEEE+' against the manufacturer's official ordering guide to confirm pinout compatibility and temperature range specifications. Ensure that any alternative components selected maintain identical serial interface timing requirements and voltage levels to guarantee system interoperability without hardware modification.

Digital To Analog Converters Selection Notes

Select this component when dual-channel precision is required within a compact footprint. The internal +2V/V gain reduces external resistor count compared to unity-gain alternatives. Consider the MAX5155 variant if the system design utilizes a +3V supply rail instead of +5V, as it offers equivalent performance characteristics optimized for lower voltage operation.

Digital To Analog Converters Part Context

This part belongs to the Maxim Integrated MAX5154/MAX5155 family of low-power serial DACs. These devices are designed for applications demanding high resolution and low power consumption in space-constrained environments. The family shares functional similarities but differs in supply voltage requirements and specific accuracy grades available in different package options.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes include the MAX5155EUE+ for +3V supply applications and other members of the MAX515x series such as the MAX5154ACEE+. Verify that replacement parts match the 16-pin QSOP physical dimensions and electrical interface timings to ensure direct board-level compatibility.

Digital To Analog Converters FAQ

How does the internal gain affect the output voltage range?

The internal gain of +2V/V doubles the reference voltage swing at the output. For example, with a 2.048V reference on the MAX5154, the output can swing from 0V to approximately 4.096V.

Can the DACs be updated independently or simultaneously?

Yes, the double-buffered input architecture allows loading input registers without updating DAC outputs, or updating both DAC registers simultaneously from their respective input registers via the serial interface.

What is the function of the PDL pin?

The Power-Down Lockout (PDL) pin disables the software shutdown feature when held low. Transitioning PDL from high to low can also asynchronously wake up the device from shutdown mode.
