MAX9107EKA-T

Overview

The MAX9107EKA-T is a dual-channel analog comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOT-23-8 surface-mount package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V with a maximum static current consumption of 700 µA. The device features TTL-compatible outputs capable of sourcing 8 mA per channel and offers a typical propagation delay of 25 ns. Key electrical specifications include a maximum input offset voltage of 1.6 mV at 5 V, an input bias current of 125 nA, and both common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) values of 86.02 dB. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel configuration providing two independent comparison circuits in a compact footprint.
• TTL-compatible output stage designed for direct interfacing with digital logic systems.
• Low-power operation optimized for battery-powered or energy-constrained applications.

Applications

• General-purpose signal threshold detection
• Voltage monitoring circuits
• Level shifting interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the EKA designation corresponds to the SOT-23-8 package variant. Ensure compatibility with the required 4.5 V to 5.5 V supply range. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate lead times as availability may vary by distributor.

Selection Notes

Select this component when a dual comparator is needed in a small SOT-23-8 package. It is suitable for applications requiring TTL outputs and moderate speed performance around 25 ns. Consider the 700 µA quiescent current for power budgeting. Compare against single-channel alternatives if only one comparator is sufficient to save board space.

Part Context

This part belongs to the MAX9107 series of low-power comparators. It shares functional similarities with other devices in the family but differs in package type and channel count. The EKA+T suffix specifies the lead-free, tape-and-reel version in the SOT-23-8 housing. It complements broader portfolios of general-purpose analog components offered by the manufacturer.

Replacement Considerations

Check for MAX9107EKA+ without the trailing T if cut-tape packaging is preferred instead of reel. Verify pinout compatibility before substituting with other dual comparators in SOT-23-8 packages.
