MAX952ESA+T

Overview

The MAX952ESA+T is an ultra-low-power, single-supply integrated circuit combining a decompensated operational amplifier, a comparator, and a precision reference within an 8-pin SO package. It operates from a 2.7V to 7V supply with a typical current of 7μA. The op amp offers 125kHz bandwidth and stability for gains of 10V/V or greater. The comparator features internal hysteresis and rail-to-rail outputs. An internal 1.2V ±2% bandgap reference connects to the inverting comparator input.

Feature Summary

• Combines a decompensated op amp, comparator, and internal 1.2V reference in one 8-pin package
• Ultra-low power consumption with 7μA typical supply current
• Comparator includes internal hysteresis for clean switching on slow signals
• Op amp and comparator outputs swing rail-to-rail

Applications

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

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm temperature range and RoHS compliance status. Ensure the ordering code matches the required package style and electrical characteristics for your design.

Selection Notes

Select this component when space is limited and low power is critical. Choose the MAX952 over the MAX951 if higher bandwidth and stability at gains of 10V/V or greater are required. Verify that the 1.2V internal reference meets your threshold requirements.

Part Context

This device belongs to the MAX951–MAX954 family of micropower mixed-signal ICs. These devices integrate multiple functions into a small footprint to simplify designs for battery-operated systems. The MAX952 specifically provides a decompensated op amp option within this series.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Cross-referencing should be performed carefully to ensure functional equivalence of the integrated op amp, comparator, and reference sections.
