MAX6078AMWT33+T

Overview

The MAX6078AMWT33+T is a precision series voltage reference from Analog Devices, featuring a fixed 3.3V output with ±0.04% initial accuracy and a maximum temperature drift of 10ppm/°C. It operates within an extended industrial temperature range of -55°C to +125°C and supports an input voltage range of 3.5V to 5.5V. The device draws a typical quiescent supply current of 15µA and provides up to 3mA of source/sink load current. It utilizes a compact 6-bump WLP package.

Feature Summary

• Provides independent force (OUTF) and sense (OUTS) pins to cancel trace voltage drops for enhanced remote sensing accuracy.
• Includes a dedicated noise reduction (NR) pin that allows external capacitor connection to filter wideband noise.
• Features an enable (EN) pin that controls operation, reducing supply current to less than 100nA during shutdown.

Applications

• High-accuracy industrial and process control systems
• Precision instrumentation equipment
• High-resolution ADCs and DACs
• Portable and handheld battery-powered systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact output voltage, package type, and grade. Ensure compatibility with the required operating temperature range and input voltage specifications before procurement.

Selection Notes

Select this component when high precision and low power consumption are critical. The 3.3V output option suits applications requiring stable references for digital logic or analog circuits. Consider the WLP package for space-constrained designs.

Part Context

This part belongs to the MAX6078 family of low-power, low-drift voltage references. The 'A' designation indicates non-1.25V output options, while 'MWT' specifies the 6-bump WLP package. The '+T' suffix denotes tape and reel packaging.

FAQ

How does the NR pin improve performance?

Connecting a capacitor to the NR pin reduces wideband noise and transient power supply noise, improving spectral noise density at higher frequencies.

What is the purpose of the OUTS pin?

The OUTS pin serves as the voltage reference output sense connection, allowing the device to regulate the load voltage directly at the point of use by compensating for line drops.
