Overview

The MCP602-I/P is a dual CMOS operational amplifier featuring rail-to-rail output performance and a 2.8 MHz gain bandwidth product. It is designed to operate from a single supply voltage as low as 2.7V while maintaining a very low typical input bias current of 1 pA. This specific variant comes in an 8-pin PDIP package, making it ideal for through-hole prototyping and educational environments.

Why Choose This Part

The CMOS architecture ensures extremely low input bias currents, which is critical for precision high-impedance circuits. The 8-PDIP package allows for easy use on breadboards and sockets without surface-mount soldering. Additionally, the input range includes ground, simplifying single-supply designs in 3V and 5V systems.

Applications

Photodiode Pre-amplifier
Utilizes the ultra-low 1 pA input bias current to convert high-impedance sensor signals into usable voltages with minimal error.
Battery-Powered Instrumentation
Efficient 230 uA per channel supply current extends operating life in portable equipment and handheld data acquisition units.
A/D Converter Driver
Provides a low-impedance buffer for driving analog-to-digital converters, aided by its rail-to-rail output swing.
Active Analog Filters
The 2.8 MHz bandwidth and unity-gain stability allow for effective audio-frequency and low-frequency signal conditioning.

Getting Started

To evaluate this part, insert it into a standard breadboard or an 8-pin DIP socket and provide a single supply between 2.7V and 6V. Ensure a 0.1uF ceramic bypass capacitor is placed close to the VDD pin (pin 8) to maintain stability. For precision designs, use a high-quality PCB layout to prevent leakage currents from affecting the high-impedance CMOS inputs.
