Microchip Technology MCP6484-E/ST Operational Amplifier

The MCP6484-E/ST is a high-precision operational amplifier (op-amp) from Microchip Technology, designed to address the needs of a wide range of applications, including automotive, industrial, medical, and consumer electronics. This particular model is part of the MCP648x family, which is well-regarded for its low power consumption and general-purpose utility.

With a quiescent current of just 450 µA, the MCP6484-E/ST is an ideal choice for battery-powered devices and energy-efficient applications. It operates over a wide supply voltage range of 1.8V to 5.5V, making it versatile for both single-supply and dual-supply operations. This flexibility allows designers to use the op-amp in various configurations without worrying about compatibility with the power supply voltage.

The device features a Gain Bandwidth Product (GBWP) of 1 MHz, which ensures sufficient bandwidth for many moderate-speed applications. Additionally, it has a low typical input bias current of 1 pA, reducing errors in high-impedance circuit designs and making it suitable for precision sensor interfaces and filter circuits.

The MCP6484-E/ST also boasts a Rail-to-Rail Input/Output (RRIO) capability, which enables the output to swing close to the supply rails and the input to be recognized from the negative rail to the positive rail. This characteristic maximizes the dynamic range in applications, especially when dealing with limited supply voltages.

Packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package), the MCP6484-E/ST is designed for surface-mount technology, providing a compact footprint for space-constrained designs. The extended temperature range of -40°C to +125°C ensures reliable performance in harsh environments, making it suitable for automotive and industrial applications where temperature extremes are common.

In summary, the Microchip Technology MCP6484-E/ST operational amplifier is a robust, low-power, and versatile component that provides designers with a reliable solution for a multitude of analog circuit applications. Its performance characteristics and packaging make it an excellent choice for those seeking a balance between power efficiency and operational capability.
