MCP601 Single Operational Amplifier IC – 2.8MHz Rail-to-Rail Op-Amp (DIP-8)

The MCP601 is a low-power, single-channel operational amplifier (op-amp) manufactured by Microchip Technology. Designed for precision analog signal processing, it combines a 2.8MHz gain-bandwidth product, low input bias current, and rail-to-rail output operation.

Operating from a single supply voltage of 2.7V to 6.0V, the MCP601 is suitable for battery-powered electronics, sensor signal conditioning, instrumentation, and embedded analog circuits.

Its CMOS input architecture provides high input impedance and low power consumption, while the DIP-8 package allows easy integration into breadboards, prototyping circuits, and through-hole PCB designs.

Key Features

• Single Operational Amplifier: One independent amplifier in a compact IC.
• 2.8MHz Gain-Bandwidth Product: Suitable for general-purpose and moderately high-speed analog signal processing.
• Rail-to-Rail Output: Output voltage can approach both supply rails under suitable load conditions.
• Low Operating Current: Approximately 230µA typical quiescent current.
• Low Input Offset Voltage: Less than 2mV under specified conditions.
• Low Input Bias Current: CMOS input architecture minimizes loading on high-impedance signals.
• Single-Supply Operation: Supports supply voltages from 2.7V to 6.0V.
• Low Shutdown Current: Approximately 1µA typical shutdown current, below 25µA maximum under specified conditions.
• High Input Impedance: Suitable for sensor interfacing and analog signal conditioning.
• DIP-8 Package: Convenient for breadboard prototyping and through-hole PCB assembly.

Technical Specifications

Pin Configuration

For the MCP601 PDIP-8 package:

Note: Verify the pin configuration against the exact MCP601 part number and manufacturer's datasheet before wiring.

Basic Connection Example

The MCP601 can be configured as a non-inverting amplifier to amplify low-voltage analog signals.

Non-Inverting Amplifier Gain:

Gain = 1 + (Rf / Rg)

Where:

• Rf = Feedback resistor between output and inverting input
• Rg = Resistor between inverting input and ground

Example:

Using Rf = 10kΩ and Rg = 10kΩ:

Gain = 1 + (10kΩ / 10kΩ) = 2

An input signal of 1V would ideally produce an output of 2V, provided the input common-mode and output voltage limits are respected.

Applications

• Analog sensor signal conditioning
• Low-power electronic circuits
• Battery-powered devices
• Data acquisition systems
• Industrial process monitoring
• Portable instrumentation
• Analog signal amplification
• Active filter circuits
• Voltage buffering
• Measurement and test equipment
• Embedded electronics projects
• Low-voltage audio signal processing

Important Notes

• The MCP601 provides rail-to-rail output operation, but its input common-mode range does not extend fully to the positive supply rail.
• The maximum recommended supply voltage is 6.0V.
• Do not exceed the specified input voltage or output current limits.
• The amplifier is intended for analog signal processing and is not designed to drive high-power loads or speakers directly.
• The gain-bandwidth product limits the available bandwidth at higher closed-loop gains.
• The shutdown pin must be configured correctly for normal operation.
• The output voltage swing depends on supply voltage and connected load.
• For stable operation, install an appropriate power supply decoupling capacitor close to the IC.
• This product is an integrated circuit and requires external components for most applications.
• Check the manufacturer's datasheet when designing precision or high-frequency circuits.
