What does precision mean for an op amp?

Are you wondering how to deal with small analog signal to transfer it to the digital domain without adding any error that could compromise the information?
This video helps you to understand what an operational amplifier is, and how to choose and use precision op amp effectively.
Precision amplifiers are op amps that have better specifications and are more accurate than your average op amp.
This video discusses the relevant parameters regarding precision. Input offset voltage, common-mode rejection ratio (CMRR), input bias current and noise are explained as well.
