This evaluation board is designed to provide an easy and flexible platform when evaluating the performance of the MCP6N16, a Zero-Drift instrumentation amplifier designed for low-voltage operation featuring rail-to-rail input and output performance.
You’ve probably heard of an Instrumentation Amplifier (INA), but you may not know the best architecture for your particular needs. There are two common approaches, so read on to quickly determine which one you should use.
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.
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.
