Overview
The MAX9019EKA+T is a dual, precision, nanopower analog comparator manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single supply voltage ranging from 1.8V to 5.5V and is housed in an SOT-23 package with eight pins. The device features low input offset voltage and ultra-low quiescent current, making it suitable for battery-powered applications. It provides push-pull outputs and includes internal hysteresis to prevent output chatter during threshold transitions.
Feature Summary
- Dual-channel configuration within a compact SOT-23-8 footprint
- Ultra-low power consumption optimized for battery-operated systems
- Precision performance with low input offset voltage specifications
- Integrated hysteresis functionality to ensure stable switching
Applications
- Battery-powered portable electronics
- Temperature sensing circuits
- Threshold detection systems
- Low-voltage monitoring applications
Procurement Notes
Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the operating temperature range aligns with system requirements. Cross-reference the full part number to distinguish between standard and extended temperature variants available within the MAX901x family.
Selection Notes
Select this component when dual comparators are required in minimal space with strict power constraints. Compare input offset voltage and propagation delay against other nanopower options if speed is critical. Verify that the 1.8V minimum supply voltage meets the lowest expected battery level. Consider the SOT-23-8 package dimensions for PCB layout compatibility.
Part Context
This device belongs to the Maxim Integrated MAX901x series of nanopower comparators. The series offers various configurations including single, dual, and quad channels with different output types and reference options. The MAX9019 specifically addresses applications requiring two precision comparators in a small surface-mount package with very low standby current.
Replacement Considerations
Direct substitutes within the same family include the MAX9017A and MAX9018B, which share similar nanopower characteristics and SOT-23 packaging. Verify channel count and output type compatibility before substitution. Consult the official datasheet for pin-to-pin equivalence and electrical parameter overlaps.
