Microchip MCP6282T-E/SN: Precision Dual Op-Amp for Low-Power Applications

The demand for efficient, high-precision analog signal processing in low-power systems continues to grow across industries such as portable medical devices, IoT sensors, and battery-powered instrumentation. Addressing this need, the MCP6282T-E/SN from Microchip Technology stands out as a precision dual operational amplifier engineered specifically for applications where power consumption and accuracy are critical.

This op-amp operates over a wide voltage range, from 2.2V to 5.5V, making it compatible with various power sources, including single-cell Li-ion batteries and regulated 3.3V or 5V rails. Its quiescent current of just 475 µA per amplifier ensures minimal power drain, significantly extending battery life in portable applications. Despite its low power draw, the MCP6282T-E/SN does not compromise on performance. It features low input offset voltage (500 µV max) and low input bias current (1 pA typical), which are essential for maintaining signal integrity and accuracy in precision circuits such as sensor interfaces, filter networks, or data acquisition systems.

The device also offers a gain bandwidth product of 550 kHz and a slew rate of 0.4 V/µs, providing sufficient speed for many DC and low-frequency AC applications. Its rail-to-rail input and output operation allows signals to swing close to the supply rails, maximizing dynamic range in low-voltage systems. Additionally, the MCP6282T-E/SN is designed with built-in EMI filtering, reducing susceptibility to high-frequency interference from wireless communications or noisy digital environments.

Housed in an 8-pin SOIC (SN) package, this op-amp is suitable for space-constrained PCB designs. It is also characterized for extended industrial temperature ranges (-40°C to +125°C), ensuring reliable operation under harsh conditions.

ICGOOFind: The Microchip MCP6282T-E/SN is an optimal choice for designers seeking a balance between precision, low power operation, and robust performance in compact dual op-amp applications.
