MAX9061EUK+T

Overview

The MAX9061EUK+T is a single-channel analog comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 5-pin SOT-23 surface-mount package. It features an open-drain output and operates on a supply voltage range of 1.0V to 5.5V with a maximum quiescent current of 700nA. The device utilizes an external reference voltage input ranging from 0.9V to 5.5V. Key electrical specifications include a propagation delay of 15µs, an input offset voltage of up to 9mV, and an input bias current of 40nA. It supports an extended operating temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated portable electronics
• High input impedance maintained even when powered down
• Input voltage range extends beyond the supply rail
• Internal filtering provides high RF immunity

Applications

• Cell phones
• Portable media players
• Notebook computers
• Electronic toys
• Portable medical devices

Procurement Notes

Verify the specific suffix 'EUK+T' against official documentation to confirm the 5-pin SOT-23 package and tape-and-reel delivery format. Ensure compatibility with the required external pull-up resistor configuration due to the open-drain output structure. Confirm RoHS compliance status through the manufacturer's datasheet before finalizing procurement specifications.

Selection Notes

Select this component when board space is constrained and ultra-low standby current is critical. The MAX9061 requires an external reference voltage between 0.9V and 5.5V, distinguishing it from variants with internal references. Designers must account for the open-drain output requirement by providing an appropriate pull-up network connected to the desired logic voltage level.

Part Context

This part belongs to the MAX9060–MAX9064 family of nanoPower single comparators designed for compact, low-voltage applications. The series offers both UCSP and SOT-23 packaging options. While other members like the MAX9062–MAX9064 feature internal 0.2V references, the MAX9061 specifically relies on an externally supplied reference voltage for threshold setting.

Replacement Considerations

The MAX9060EUK+T serves as a functional substitute within the same family, differing primarily in having a noninverting input instead of the MAX9061's inverting input.
