MAX6070BAUT18+T

Overview

The MAX6070BAUT18+T is a low-noise, high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output of 1.8V with an initial accuracy of ±0.08% and a maximum temperature drift of 8ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V and consumes a typical quiescent current of 200µA at +25°C. It features a noise filter option for wideband applications and supports sourcing and sinking up to 10mA of load current. The component is housed in a compact 6-pin SOT23 package and is specified over the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides stable performance over temperature and time with high initial accuracy
• Features a dedicated filter input pin to lower high-frequency noise for wideband applications
• Includes enable/shutdown control functionality to reduce power consumption

Applications

• High-Accuracy Industrial and Process Control
• Precision Instrumentation
• High-Resolution ADCs and DACs
• Precision Current Sources

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.08% accuracy grade rather than the higher precision 'A' grade. Confirm the '+T' suffix denotes tape-and-reel packaging. Ensure the ordering code matches the required 1.8V output specification. Check for AEC-Q100 qualification if automotive compliance is necessary, as this may require a different suffix variant.

Selection Notes

Select this part when system requirements demand a fixed 1.8V reference with moderate precision (±0.08%) and low power consumption. The MAX6070 variant is suitable for applications requiring high-frequency noise reduction via the external filter capacitor. Consider the MAX6071 if faster settling times are needed without the filter penalty. Evaluate thermal dissipation capabilities within the SOT23 package for the specific load conditions.

Part Context

This component belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The family offers various output voltages including 1.25V, 2.5V, and 3.3V options. The MAX6070 includes a filter pin for noise reduction, while the MAX6071 offers faster transient response. Both families utilize a 6-pin SOT23 or WLP package to minimize board space.

FAQ

What is the function of the FILTER pin on the MAX6070?

Connecting a 0.1µF capacitor from the FILTER pin to ground provides high-frequency bypass, lowering the output noise density for wideband applications.

How does the MAX6070 differ from the MAX6071 regarding settling time?

The MAX6070 has a slower turn-on and enable settling time due to its internal filtering, whereas the MAX6071 offers significantly faster settling times without the filter option.
