Overview
The MAX9022AUA+T is a dual micropower comparator in an 8-pin µMAX package. It operates from a single supply of 2.5V to 5.5V or dual supplies of ±1.25V to ±2.75V. The device consumes 2.8µA per comparator and features a typical propagation delay of 3µs. It includes 4mV internal hysteresis, rail-to-rail output swing, and no phase reversal for overdriven inputs. The common-mode input range extends from the negative supply to within 1.1V of the positive supply.
Feature Summary
- Micropower consumption with 2.8µA supply current per comparator
- Internal 4mV hysteresis for noise immunity
- Rail-to-rail output voltage swing
- No phase reversal for overdriven inputs
Applications
- Battery-powered portable systems
- Mobile communications
- Sensor-signal detection
- Photodiode preamps
- Threshold detectors/discriminators
Procurement Notes
Verify the specific suffix +T indicates tape and reel packaging. Confirm RoHS compliance status associated with the plus sign. Ensure the µMAX package code matches design requirements. Check availability as distribution may vary by region.
Selection Notes
Select this component for applications requiring low power and small footprint. The dual configuration fits space-constrained designs. Verify input signal speed against the 3µs propagation delay. Ensure supply voltage stays within the 2.5V to 5.5V range.
Part Context
Part of the MAX9021/MAX9022/MAX9024 family of micropower comparators. The MAX9022 variant provides two independent channels. Available in multiple packages including SOT23, SO, and µMAX. Optimized for single-supply operation in portable electronics.
Replacement Considerations
MAX9022AUK+T (SOT23-8)
FAQ
What is the purpose of the internal hysteresis?
The 4mV internal hysteresis provides noise immunity and prevents oscillations even with slow-moving input signals.
Can the MAX9022AUA+T operate from dual supplies?
Yes, it can operate from dual supplies ranging from ±1.25V to ±2.75V.
