Overview
The MAX9075EUK-T is a single-supply analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.1V to 5.5V and consumes 3µA per comparator. The device features a propagation delay of 580ns, an input offset voltage of ±1mV (typical), and an input bias current of -5nA (typical). It utilizes a push-pull output stage capable of rail-to-rail swing with loads up to 2mA. The component is housed in a 5-pin SOT-23 package and functions across a temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low power consumption of 3µA per comparator
- Rail-to-rail push-pull output drivers supporting loads up to 2mA
- Ground-sensing inputs with no differential clamp across inputs
- No output phase inversion for overdriven inputs
Applications
- Battery-powered systems
- Threshold detectors/discriminators
- Keyless entry systems
- IR receivers
- Digital line receivers
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'E' designation aligns with the industrial temperature range (-40°C to +85°C) and the 'U' corresponds to the SOT-23 package type. Ensure compatibility with single-supply operation requirements between 2.1V and 5.5V before procurement.
Selection Notes
Select this component when low quiescent current is critical for battery life. The rail-to-rail output capability simplifies interfacing with TTL/CMOS logic without additional level shifting. Verify that the 580ns propagation delay meets system timing constraints compared to faster alternatives.
Part Context
This part belongs to the MAX9075/MAX9077 family of low-cost, ultra-small comparators. The MAX9075 variant provides a single comparator channel, whereas the MAX9077 offers dual channels. Both share identical electrical characteristics and are optimized for portable applications requiring minimal footprint and power usage.

FAQ
Does the MAX9075 have a differential clamp between its inputs?
No, unlike many other comparators, the MAX9075 has no differential clamp, allowing the differential input voltage range to extend rail-to-rail.
What is the common-mode input voltage range?
The common-mode input voltage range extends from -0.2V to VCC - 1.2V.
