MAX5174AEEE+

Digital To Analog Converters Overview

The MAX5174AEEE+ is a low-power, serial, voltage-output, 12-bit digital-to-analog converter (DAC) featuring a precision output amplifier in a 16-pin QSOP package. It operates from a single +5V supply with a typical supply current of 280µA, reducing to 1µA in shutdown. The device incorporates a glitch-free output circuit at power-up and supports SPI/QSPI/MICROWIRE-compatible 3-wire serial interfaces.

Digital To Analog Converters Feature Summary

• Glitch-free output voltage during power-up
• Rail-to-rail output amplifier
• Adjustable output offset capability
• User-programmable digital output pin

Digital To Analog Converters Applications

• Industrial Process Controls
• Motion Control
• Automatic Test Equipment (ATE)
• Remote Industrial Controls
• µP-Controlled Systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A' for ±1 LSB INL accuracy against the datasheet specifications. Confirm the operating temperature range matches the application requirements (-40°C to +85°C). Ensure the +5V supply voltage aligns with system constraints, as the MAX5176 variant is designed for +3V operation. Check for RoHS compliance status on the specific manufacturing lot.

Digital To Analog Converters Selection Notes

Select this component for applications requiring low power consumption and high accuracy in a compact package. The MAX5174 is suitable for systems needing a +5V supply, whereas the MAX5176 serves +3V designs. Consider the MAX5170 or MAX5172 if 14-bit resolution is required, as they are pin-compatible upgrades. Verify interface compatibility with the host microcontroller's serial protocol.

Digital To Analog Converters Part Context

The MAX5174AEEE+ belongs to the MAX5174/MAX5176 family of low-power, serial DACs. It is part of a broader portfolio that includes 14-bit versions (MAX5170/MAX5172) and devices with internal references (MAX5120/MAX5121). This family is designed for space-constrained industrial and control applications requiring precise analog signal generation.

Digital To Analog Converters Replacement Considerations

The MAX5176AEEE+ is a pin-compatible alternative operating from a single +3V supply instead of +5V. For higher resolution needs, the MAX5170AEEE+ and MAX5172AEEE+ offer 14-bit performance while maintaining the same 16-pin QSOP footprint and pinout configuration.

Digital To Analog Converters FAQ

How does the MAX5174 handle output glitches during power-up?

The device incorporates a proprietary on-chip circuit that keeps the output voltage virtually glitch-free, limiting glitches to a few millivolts during power-up.

What is the function of the User-Programmable Output (UPO) pin?

The UPO pin allows serial control of external components, reducing the number of microcontroller I/O pins required. Its state can be set via the serial input commands.

Can the reference input accept AC signals?

Yes, the reference input is capable of accepting DC and offset AC signals, provided the voltage remains between 0 and VDD - 1.4V.
