Op amp current booster circuit

Web15 de out. de 2024 · An op-amp with 1MHz GBW has 10kHz of bandwidth at gain of 100 (=40dB). Since you need 20kHz of bandwidth, a single op-amp will not be enough. The current through any resistor in the amplifier should not exceed 10 mA. Web7 de fev. de 2024 · This type of amplifier circuit is used in our first example (Reply 4). Vout = - Vin R2 / R1 or Vout / Vin = - R2/R1 ( Note: this formula is not the same as for the non-inverting amplifier) The input resistance Rin is just R1. However with modern op amps we can use large value resistors.
