High-Performance Instrumentation Amplifiers

Our instrumentation amplifiers include internal matched feedback and are ideal for data acquisition applications. Their ability to accurately extract a small signal in the presence of a large common mode makes these instrumentation amplifiers ideal for sensor amplification. Electromagnetic Interference (EMI) filtering on select devices maintains excellent performance in the most demanding environments.

Using high-precision architectures enables superior DC performance, regardless of operating conditions
Low noise and additional EMI filtering on the inputs provide additional protection in electrically noisy environments
Small packages, such as leadless DFNs, are ideal for space-constrained designs
A wide operating temperature range of –40°C to +125°C provides a robust solution even at extreme temperatures

How Do I Eliminate Flicker Noise in My Amplifier Design?

While there are many different sources of noise within an operational amplifier, perhaps the most mysterious and frustrating noise source is what is known as flicker noise. How does one deal with this dominating, low frequency noise? If 1/f noise is a big concern, then selecting a zero-drift amplifier is the best solution.

MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design

The MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design demonstrates the performance of Microchip's MCP6N11 instrumentation amplifier (INA) and a traditional three op amp INA using Microchip's MCP6V26 and MCP6V27 auto-zeroed op amps. The input signal comes from an RTD temperature sensor in a Wheatstone bridge. Real world interference is added to the bridge's output, to provide realistic performance comparisons.
