Pinout List (8 Pins)
Pin Number Pin Name Pin Description 1 Output A Output of the first op-amp in the quad package. This is where the processed signal from the first amplifier is delivered. 2 Inverting Input A The inverting input (−) of the first op-amp. This is where the negative feedback signal is applied. 3 Non-Inverting Input A The non-inverting input (+) of the first op-amp. This is where the positive input signal is applied. 4 V− (Ground) This is the negative Power supply pin. In the case of single-supply operation, this is typically ground (0V). 5 Non-Inverting Input B The non-inverting input (+) of the second op-amp. 6 Inverting Input B The inverting input (−) of the second op-amp. 7 Output B Output of the second op-amp. 8 V+ (Positive Power Supply) This is the positive power supply pin. In a single-supply operation, this is typically a positive voltage.General Circuit Principles
Operational Amplifier Basics: The TLC2272AIDR is a low-power, quad op-amp, which means it contains four independent operational amplifiers with the same electrical characteristics housed in a single package. Each op-amp can amplify small voltage differences between two input pins (the non-inverting and inverting inputs) to produce a larger output voltage at the output pin. Single-Supply Operation: The op-amps in the TLC2272AIDR can operate on a single power supply, which means both the positive and negative voltage rails (V+ and V−) can be tied to the same ground reference. This makes the part very useful in battery-powered circuits. Gain Control: The gain of each amplifier can be set using external resistors. Inverting or non-inverting amplifier configurations can be used depending on the application.Frequently Asked Questions (FAQ)
