INVERTING AMPLIFIER SCHEMATIC PCB TLV170
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 the non-inverting node, which is ground in this design. D1 indicates the power, all connection can be done using CN1 header connector, Capacitors, Resistors, LEDs are SMD components size 0805. Op-Amp TLV170 from Texas Instruments.
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 dividers.
This 5V single-supply window comparator utilizes a dual open-collector comparator and two trimmer potentiometer to set the window voltage. 2X TLV1701 was used in this design due to its low power consumption and open collector output, which allows the output to be pulled up as high as 36 V.
