MAX951EUA-T

Overview

The MAX951EUA-T is a specialized analog integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, belonging to the MAX951 series. It functions as a single-channel device combining an operational amplifier, comparator, and voltage reference within one package. The component operates within a temperature range of -40°C to +85°C and utilizes a uMAX-8 surface-mount package. Key electrical specifications include a gain-bandwidth product of 20 kHz, an input bias current of 50 pA, and an input offset voltage of 14 mV. It draws a typical supply current of 7 uA.

Feature Summary

• Integrates operational amplifier, comparator, and voltage reference in a single channel
• Designed for ultra-low-power applications with minimal supply current consumption
• Supports single-supply operation for simplified system design

Applications

• Low-power analog signal conditioning circuits
• Battery-operated measurement systems requiring high impedance inputs
• Smart card interface logic and power management
• Precision sensor signal amplification
• Portable instrumentation with strict power constraints

Procurement Notes

Verify availability status carefully as this component may be subject to limited supply or discontinuation notices. Confirm the specific suffix requirements for tape-and-reel packaging versus tube packaging. Ensure compatibility with existing PCB footprints for the uMAX-8 package before ordering. Check for any recent product change notifications that might affect long-term viability.

Selection Notes

Select this part when a combined op-amp, comparator, and reference solution is required to minimize board space and component count. Consider the 20 kHz bandwidth limit for high-speed applications where faster response times are needed. Evaluate the 14 mV input offset voltage against precision requirements. Verify that the 50 pA input bias current meets the source impedance constraints of the connected circuitry.

Part Context

This device is part of the MAX951 family of special-purpose amplifiers from Maxim Integrated, now part of Analog Devices. These components are designed to provide multiple analog functions in a compact form factor, reducing overall system complexity. The MAX951 series targets applications where power efficiency and integration density are critical design drivers.
