Microchip MCP6562-E/MS Dual Op-Amp: Features, Applications, and Technical Specifications

The Microchip MCP6562-E/MS is a dual general-purpose operational amplifier (op-amp) designed to operate from a low voltage supply, ranging from 1.8V to 5.5V, making it ideal for battery-powered and portable applications. This op-amp combines low power consumption with rail-to-rail input and output operation, ensuring a wide dynamic range even at low supply voltages. With its high gain bandwidth product of 300 kHz (typical) and a low quiescent current of just 50 µA per amplifier, the device offers an excellent balance between performance and energy efficiency. It is housed in an MSOP-8 package, which is suitable for space-constrained PCB designs.

A key feature of the MCP6562 is its input common-mode voltage range that extends beyond both supply rails, enabling flexible signal conditioning in systems where the input signal may approach or exceed the supply voltage. Additionally, the op-amp provides stable operation with capacitive loads up to 400 pF, which is beneficial for driving analog-to-digital converter (ADC) inputs or long cables. The device is also characterized by a low input offset voltage of 0.5 mV (typical), enhancing accuracy in precision applications.

The MCP6562-E/MS is widely used in various fields, including portable medical devices, sensor interface circuits, battery management systems, and wearable electronics. Its low-voltage operation makes it suitable for signal conditioning in IoT nodes, where power efficiency and small form factors are critical. It is also commonly employed in active filter designs, voltage followers, and comparator circuits due to its rail-to-rail output swing and stable performance.

Technical specifications include a phase margin of 60°, which ensures stability under various operating conditions, and a temperature range of -40°C to +125°C, allowing deployment in industrial environments. The device is ESD-protected and offers robust performance in demanding applications.
