Microchip MCP652-E/SN Dual Op-Amp: Features, Applications, and Technical Specifications

The Microchip MCP652-E/SN is a dual operational amplifier (op-amp) that combines low-power consumption with rail-to-rail input and output operation, making it a versatile solution for a wide range of analog circuit designs. This op-amp is housed in a compact 8-pin narrow SOIC package (SN), ideal for space-constrained applications.

Key Features

The MCP652-E/SN stands out with its ultra-low quiescent current of just 22 µA per amplifier, which is crucial for battery-powered and portable devices. Its rail-to-rail input and output capability allows the signals to swing close to both power supply rails, maximizing the dynamic range in low-voltage systems. It operates over a wide power supply voltage range from 1.8V to 5.5V, supporting both single-supply and split-supply configurations. Additionally, it offers a gain bandwidth product of 300 kHz and is designed with EMI hardening, reducing the susceptibility to high-frequency interference.

Primary Applications

This op-amp is engineered for applications where power efficiency and performance are critical. Its primary uses include:

Sensor Interface and Signal Conditioning: Perfect for amplifying small signals from sensors (e.g., temperature, pressure, optical) in industrial and automotive systems.

Portable and Battery-Powered Equipment: Its low current draw extends battery life in devices like handheld meters, medical monitors, and wearable technology.

Active Filters: Used to implement low-power, low-frequency active filter circuits.

ADC Driver and Buffer: Serves as an effective buffer for analog-to-digital converters (ADCs) due to its rail-to-rail output swing.

Portable Test and Measurement Equipment: Provides accurate amplification in compact, mobile instruments.
