Overview

The MCP6401T-E/OT is a general-purpose, single operational amplifier designed for low-power applications. It features a 1 MHz gain bandwidth product and rail-to-rail input and output operation while consuming only 45uA of typical quiescent current. This amplifier is unity-gain stable and operates from a supply voltage as low as 1.8V.

Why Choose This Part

The MCP6401 offers a strong balance between power consumption and speed, providing 1 MHz bandwidth at just 45uA. Its rail-to-rail input/output capability maximizes dynamic range on low-voltage rails down to 1.8V. Additionally, the lack of phase reversal ensures stable performance even when input signals exceed the supply rails.

Applications

Battery-Powered Instrumentation
Utilizes the 45uA low quiescent current to extend battery life in portable handheld devices.
Sensor Signal Conditioning
The 1 pA typical input bias current makes it ideal for high-impedance sensor interfaces.
Active Analog Filters
Provides a 1 MHz bandwidth suitable for low-frequency filtering in data acquisition systems.
Automotive Sensor Interfaces
Supports extended temperature ranges from -40degC to 125degC for cabin or engine-peripheral electronics.

Getting Started

When designing with the MCP6401, ensure a 0.1uF bypass capacitor is placed close to the VDD pin for stability. Since it is unity-gain stable, it can be used in simple voltage follower configurations without external compensation. Evaluation can be performed using generic SOT-23 breakout boards or by simulating designs in MPLAB Mindi Analog Simulator.
