Pin Number Pin Name Pin Description 1 V- Negative power supply pin (typically ground or negative rail) 2 In+ Non-inverting input of the operational amplifier 3 Out Output of the operational amplifier 4 In- Inverting input of the operational amplifier 5 V+ Positive power supply pin (typically positive rail)Pin Functions in Detail:
Pin 1 (V-): This is the negative power supply pin. The OPA333 requires a dual power supply or a single supply with a negative voltage for proper operation. The voltage level on this pin is typically ground in most designs, but it can also be connected to a negative supply depending on the system configuration. Pin 2 (In+): The non-inverting input of the op-amp. Signals applied to this pin will appear at the output with the same polarity (non-inverted). It is one of the key inputs for signal amplification in the operational amplifier circuit. Pin 3 (Out): This is the output pin of the op-amp. It provides the amplified signal corresponding to the difference between the inputs, In+ and In-. The output voltage is subject to the power supply constraints, so it can't exceed the supply rails. Pin 4 (In-): The inverting input of the op-amp. Signals applied to this pin will appear at the output with the opposite polarity (inverted). This pin is used in feedback configurations and signal inversion in the circuit. Pin 5 (V+): The positive power supply pin. It is the source for the positive voltage necessary for the operation of the op-amp. This pin, along with the V- pin, determines the voltage range within which the op-amp can output signals.Circuit Principle Instructions for OPA333AIDBVR:
The OPA333AIDBVR is a precision operational amplifier, designed to provide high accuracy and low offset voltage. Below is a general circuit principle:
Op-Amp Configuration: The OPA333 can be used in a variety of configurations such as voltage followers, differential amplifiers, inverting amplifiers, and non-inverting amplifiers. Its rail-to-rail input and output allow it to function effectively with low voltage supplies.
Biasing: Proper biasing must be applied to the op-amp to ensure correct operation. The op-amp requires both positive and negative supply voltages for optimal performance, and improper biasing can lead to non-linearity or clipping of the output signal.
Gain: The OPA333 provides stable gain when used in feedback configurations. The gain is set by external resistors (inverting or non-inverting configurations) according to the application needs.
Output Swing: The op-amp has a rail-to-rail output, meaning the output can swing from the negative supply rail (V-) to the positive supply rail (V+), making it suitable for low voltage operation.
