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

Window Comparator/Voltage Sensitive Switch TLV1701

Window Comparator/Voltage Sensitive Switch TLV1701 This circuit utilizes two comparators in parallel to determine if a signal is between two reference voltages. If the signal is within the window, the output is high. If the signal level is outside of the window, the output is low. For this design, the reference voltages are generated from a single supply with voltage
