MAX954EPA+

Overview

The MAX954EPA+ is a single-supply integrated circuit combining a decompensated operational amplifier, a comparator, and no internal reference within an 8-pin plastic DIP package. It operates from a supply voltage range of 2.4V to 7V with a typical supply current of 5μA. The op amp features a gain bandwidth product of 125kHz and stability for gains of 10V/V or greater. Both the op amp and comparator outputs swing rail-to-rail, and the common-mode input voltage extends from the negative rail to within 1.6V of the positive rail.

Feature Summary

• Combines a decompensated op amp and comparator in a single 8-pin package
• Ultra-low power consumption with microampere-level supply current
• Rail-to-rail output capability for both amplifier and comparator stages
• Internal comparator hysteresis ensures clean switching

Applications

• Battery-powered portable instruments
• Low-frequency local-area alarms and detectors
• Photodiode preamplifiers
• Smart cards
• Infrared receivers for remote controls

Procurement Notes

Verify the specific suffix 'EPA' confirms the -40°C to +85°C temperature range and 8-pin Plastic DIP package. Confirm RoHS compliance status via the manufacturer's documentation. Check for obsolescence notices as this component family may have limited availability.

Selection Notes

Select the MAX954 variant specifically when a decompensated op amp with 125kHz bandwidth and stability at gains of 10V/V or greater is required. Choose this part over the MAX953 if higher speed is needed, noting that the MAX954 lacks the internal bandgap reference found in the MAX951/MAX952 series.

Part Context

This device belongs to the MAX951–MAX954 family of ultra-low-power, single-supply amplifiers. The MAX954 specifically integrates a decompensated op amp and a comparator without an internal reference. It is designed for applications requiring minimal power consumption while maintaining signal integrity in battery-operated systems.

Replacement Considerations

Direct pin-compatible substitutes include other variants within the MAX951–MAX954 family, such as the MAX954ESA (SO package) or MAX954EUA (µMAX package), provided the package form factor change is acceptable.
