MAX992EUA

Comparators Overview

The MAX992EUA is a dual micropower comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V or dual supplies of ±1.25V to ±2.75V. The device features low input bias current of 1pA and low input offset voltage of 5mV at 5.5V. It provides high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 80dB typical. Propagation delay is typically 210ns with hysteresis of ±2.5mV. It is housed in an 8-UMAX package and operates between -40°C and +85°C.

Comparators Procurement Notes

Verify the specific suffix for the requested package variant, as the MAX992 series includes multiple packaging options such as SOIC and UMAX. Confirm availability status directly with authorized distributors, as supply constraints may affect lead times. Ensure the selected part number matches the required operating temperature range and electrical specifications for the target application environment.

Comparators Selection Notes

Select this component when dual comparators are required in space-constrained designs with strict power consumption limits. The rail-to-rail output simplifies interfacing with digital logic families without additional level shifting. Consider the propagation delay characteristics against system timing requirements. Verify that the input voltage range remains within the specified limits for the chosen supply voltage configuration.

Comparators Part Context

This device belongs to the Maxim Integrated micropower comparator family, designed for efficiency in battery-operated systems. It shares architectural similarities with other low-power analog devices from the manufacturer but offers distinct dual-channel integration. The UMAX package provides a compact footprint suitable for dense PCB layouts compared to larger industrial packages.

Comparators Replacement Considerations

Check for direct pin-compatible alternatives within the same product family if the exact suffix is unavailable. Verify that any substitute maintains the same supply voltage range and output type compatibility.
