INVERTING AMPLIFIER SCHEMATIC PCB USING TLV170

INVERTING AMPLIFIER SCHEMATIC PCB CALCULATION USING TLV170 Design Description This design inverts the input signal, Vi, and applies a signal gain of –2V/V. The input signal typically comes from a low-impedance source because the input impedance of this circuit is determined by the input resistor, R3. The common-mode voltage of an inverting amplifier is equal to the voltage connected to
