Instrumentation Amplifiers (INA)

Microchip offers INAs (Instrumentation Amplifiers) that include internal matched feedback and are ideal for data acquisition applications. The ability to extract a small signal in the presence of a large common-mode makes INAs ideal for sensor amplification. Depending on the device, INA gain can be adjusted using external resistors or programmable through software control. EMI (electromagnetic interference) filtering on select devices maintains excellent performance in the most demanding environments.
