Microchip MCP6072T-E/MNY: A Precision CMOS Dual Op-Amp for Low-Power Applications

In the realm of analog signal conditioning, operational amplifiers (op-amps) are fundamental building blocks. For applications where power consumption and accuracy are paramount, the selection of the right op-amp becomes critical. The Microchip MCP6072T-E/MNY stands out as a premier choice, offering a compelling combination of high precision and remarkably low power consumption.

This dual operational amplifier is built on advanced CMOS technology, which is the cornerstone of its performance advantages. A key specification is its ultra-low quiescent current of just 20 µA per amplifier, making it exceptionally suitable for battery-powered and portable devices where extending operational life is a primary design goal. Despite this minimal power draw, the MCP6072T-E/MNY does not compromise on accuracy. It features low input offset voltage (250 µV max) and a minimal input bias current (1 pA typical), ensuring precise signal amplification with minimal error—a crucial requirement for sensor interfaces, precision filters, and instrumentation systems.

The device operates over a wide supply voltage range from 2.3V to 5.5V, providing designers with flexibility for both 3.3V and 5V systems. Furthermore, it exhibits a rail-to-rail input and output swing, maximizing the dynamic range and enabling signals to utilize the entire supply spectrum, which is particularly beneficial in low-voltage applications. Housed in a space-saving 8-pin DFN package, it is also designed for compact PCB layouts.

Typical applications leveraging its strengths include:

Portable medical diagnostic equipment

Long-life battery-powered sensors and IoT nodes

Precision analog filters and active gain stages

Portable test and measurement instruments

Energy harvesting systems
