MAX6078AMWT25+T

Overview

The MAX6078AMWT25+T is a precision voltage reference from Analog Devices, featuring a fixed 2.5V output with ±0.04% initial accuracy. It operates within an input voltage range of 2.3V to 5.5V and draws a maximum quiescent current of 15µA. The device provides a 3mA source/sink load current capability and maintains a low temperature drift of 10ppm/°C over the extended industrial temperature range of -55°C to +125°C. Packaged in a compact 6-bump Wafer Level Package (WLP), it includes an enable pin for shutdown control and an NR pin for wideband noise reduction.

Feature Summary

• Provides high-precision voltage regulation with minimal power consumption suitable for battery-operated systems
• Features independent force and sense outputs to eliminate trace resistance errors
• Includes a dedicated noise reduction input for filtering wideband interference

Applications

• High-resolution analog-to-digital converters
• Precision instrumentation circuits
• Portable handheld measurement devices

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure the selected variant matches the required output voltage and accuracy grade for your design specifications before finalizing procurement orders.

Selection Notes

Select this component when system design requires ultra-low supply current combined with high long-term stability. The WLP package is optimal for applications with strict board area constraints. Verify that the input voltage remains above the specified dropout threshold under all operating load conditions.

Part Context

This part belongs to the MAX6078 family of low-power, low-drift voltage references manufactured by Analog Devices. The family offers multiple fixed output voltage options and utilizes either 6-bump WLP or 8-pin TDFN-EP packages to accommodate various space-constrained electronic designs.

FAQ

How does the Noise Reduction (NR) pin function?

Connecting a capacitor between the NR pin and ground filters wideband noise. A 0.01µF capacitor reduces spectral noise density at 100Hz.

What is the purpose of the separate OUTF and OUTS pins?

OUTF supplies current to the load while OUTS senses the voltage at the load point. This Kelvin connection cancels voltage drops across PCB traces.
