Overview

This design is used to buffer signals by presenting a high input impedance and a low output impedance. This circuit is commonly used to drive low-impedance loads, analog-to-digital converters (ADC) and buffer reference voltages. The output voltage of this circuit is equal to the input voltage.
Features
  • Input: ±10 V
  • Output: ±10 V
  • Frequency: 100 kHz
  • Supply: ±15 V
