Overview
The MAX9022AKA+T is a dual micropower comparator from the MAX9021/MAX9022/MAX9024 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V and consumes only 2.8µA of supply current per comparator across the -40°C to +125°C temperature range. The device features a typical propagation delay of 3µs and includes built-in 4mV hysteresis for noise immunity. It utilizes an 8-pin SOT23 package (K8) and offers rail-to-rail output swing with no phase reversal for overdriven inputs.
Feature Summary
- Ultra-low power consumption of 2.8µA per comparator
- Built-in 4mV internal hysteresis for noise immunity
- Rail-to-rail output swing capability
- No phase reversal for overdriven inputs
Applications
- Battery-powered portable systems
- Mobile communications devices
- Sensor-signal detection circuits
- Photodiode preamplifiers
- Digital line receivers
Procurement Notes
Verify the specific ordering suffix K8 corresponds to the 8-pin SOT23 package configuration required for your design. Confirm RoHS compliance status indicated by the plus sign in the part number. Check current availability as distribution may vary. Ensure the operating voltage range of 2.5V to 5.5V matches your system requirements before procurement.
Selection Notes
Select this component when low power consumption is critical alongside small footprint requirements. The dual-channel configuration fits applications needing two comparators in minimal space. Consider the 3µs propagation delay for timing-sensitive designs. Verify that the common-mode input range extending to the negative supply meets your signal conditioning needs.
Part Context
This part belongs to the MAX9021/MAX9022/MAX9024 series of micropower comparators. The MAX9022 specifically provides dual channels, unlike the single-channel MAX9021 or quad-channel MAX9024. All variants share similar electrical characteristics including low supply current and fast response times, optimized for portable single-supply applications.
Replacement Considerations
Direct substitutes within the same family include MAX9022AUA+T (μMAX package) and MAX9022ASA+T (SO package). These offer identical electrical performance but differ in physical package dimensions. Verify pin compatibility and thermal dissipation requirements when switching between SOT23, μMAX, and SO packages.
