Microchip MCP6072-E/SN: A Precision CMOS Dual Op-Amp for Low-Power Applications

In the realm of analog signal conditioning, the operational amplifier remains a fundamental component, and the quest for devices that combine precision, low power consumption, and robust performance is ongoing. The Microchip MCP6072-E/SN stands out as a premier solution, specifically engineered to meet the demanding requirements of modern low-power and portable applications.

This integrated circuit is a dual operational amplifier fabricated with advanced CMOS technology. This technological foundation is key to its exceptional performance characteristics, most notably its remarkably low quiescent current of just 20 µA per amplifier. This minimal power draw makes it an ideal candidate for battery-powered devices where extended operational life is paramount, such as in portable medical equipment, handheld meters, and remote wireless sensors.

Beyond its power efficiency, the MCP6072-E/SN delivers outstanding precision. It features a very low input offset voltage of 250 µV (max) and an impressively low input bias current of 1 pA (typ). These specifications are critical for applications requiring accurate signal amplification of small sensor outputs, such as thermocouples, strain gauges, or pressure transducers, as they minimize errors in the measurement chain.

The device operates on a single supply voltage ranging from 2.3V to 5.5V, further enhancing its suitability for designs powered by two-cell batteries or a single lithium-ion cell. Despite its low-power operation, it maintains a usable gain bandwidth product of 50 kHz and incorporates rail-to-rail input and output operation. This allows the input and output signals to swing very close to the power supply rails, maximizing the dynamic range in low-voltage systems.

Housed in a compact 8-pin narrow SOIC package (SN), the MCP6072-E/SN offers a space-saving footprint for densely populated PCBs. Its design also ensures a high degree of stability, featuring built-in EMI filtering and a stable operation with capacitive loads up to 300 pF, which simplifies design-in and improves reliability.

ICGOODFIND: The Microchip MCP6072-E/SN is a superior choice for designers prioritizing precision and power efficiency. Its combination of ultra-low power consumption, excellent DC accuracy, and rail-to-rail operation in a small form factor makes it an exceptionally versatile dual op-amp for a wide array of portable and battery-conscious analog designs.
