Overview
The MAX9141EKA is a single-channel analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It features a 40 ns response time and operates on a supply voltage range of 2.7 V to 5.5 V. The device draws 320 uA of operating current and provides a CMOS/TTL output type with a per-channel output current of 4 mA. Key electrical parameters include an input offset voltage (Vos) of 2 mV, input bias current (Ib) of 320 nA, and input offset current (Ios) of 120 nA. It is housed in an SOT-23-8 package and supports surface mount installation.
Feature Summary
- Integrates a latch function for general-purpose comparison applications
- Supports rail-to-rail signal input capabilities
- Compatible with both CMOS and TTL logic output standards
Applications
- Low-power portable electronic devices
- General-purpose signal threshold detection
- Battery-operated systems requiring low quiescent current
Procurement Notes
Verify the specific suffix 'EKA' against official datasheets to confirm the SOT-23-8 package and tape-and-reel shipping configuration. Ensure the component meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times prior to procurement planning.
Selection Notes
Select this component when a single-channel comparator with integrated latching is required for space-constrained designs. The SOT-23-8 package offers a compact footprint suitable for high-density PCB layouts. Consider the 2 mV input offset voltage and 40 ns propagation delay for applications demanding moderate precision and speed within a low-power budget.
Part Context
This part belongs to the MAX9141 series of low-power comparators from Maxim Integrated. It is designed for battery-powered applications where minimizing power consumption is critical while maintaining reliable signal switching performance. The series typically includes variants with different packaging options to suit various assembly needs.
Replacement Considerations
Consult official replacement guides for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the 2.7 V to 5.5 V supply range and SOT-23-8 form factor.
