MAX985EUK-TG002

Comparators Overview

The MAX985EUK+T is a micropower, low-voltage analog comparator manufactured by Analog Devices Inc. (Maxim Integrated). It features rail-to-rail inputs and outputs, operating on a single supply voltage ranging from 2.5V to 5.5V. The device incorporates CMOS push-pull output stages compatible with TTL logic levels. Key electrical specifications include a maximum propagation delay of 450ns, a typical CMRR and PSRR of 80dB, and a maximum input offset voltage of 5mV at 5.5V. It draws a maximum static current of 24µA and has an input bias current of 1pA at 5.5V. The component operates within a temperature range of -40°C to +85°C and is housed in a SOT-23-5 package.

Comparators Feature Summary

Comparators Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact tape-and-reel quantities or packaging variations. Confirm RoHS compliance status as regulatory requirements may evolve. Ensure the ordering part number matches the required package type and temperature grade before finalizing procurement orders.

Comparators Selection Notes

Select this component when system design requires minimal power consumption alongside rail-to-rail signal handling. The low input bias current makes it suitable for high-impedance sensor interfaces. Verify that the 450ns propagation delay meets the timing requirements of the target application circuit.

Comparators Part Context

This device belongs to the MAX985/MAX986/MAX989 family of micropower comparators. These components share common characteristics such as low-voltage operation and rail-to-rail I/O. The MAX985 specifically denotes the single-channel configuration within this series, distinguishing it from dual or quad variants.

Comparators Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic replacements must match the SOT-23-5 package, 2.5V-5.5V supply range, and comparable propagation delay specifications.
