Op Amp Precision Design: DC Errors - Microchip Technology
AN1177. op amp Precision design : DC Errors Author: Kumen Blake DC SPECIFICATIONS. Microchip Technology Inc. There are a small number of DC specifications that describe Errors at the input of an op amp . This section INTRODUCTION organizes these specifications into those related to the input offset and the others related to input bias Engineers that use op amps in their circuits; especially currents. those new to analog or op amp circuit design . Also intended for engineers that want to understand op amp Ideal op amp DC specifications. Figure 1 shows the ideal, DC model for op amps (the Description external circuitry is not shown). All error sources are ignored and the open-loop gain (AOL) is infinite. The This application note covers the essential background output voltage is related to the input voltages as shown information and design theory needed to design a in Equation 1. Precision DC circuit using op amps. Topics include: op amp DC Specifications VN.
