OPA2376AIDR Pin Function Specifications
The OPA2376 is a precision op-amp that features low offset voltage, low drift, and high accuracy. Below is a table describing the pin functions in a SOT-23-5 package:
Pin Number Pin Name Pin Function 1 V+ Positive power supply input. This is the positive voltage supply pin for the operational amplifier. Typically ranges from +2.7V to +36V or +18V (single supply). 2 Input B Inverting input. This is the inverting terminal of the operational amplifier. The input voltage here is amplified and inverted in relation to the output voltage. 3 Output Output pin. The output voltage reflects the amplified difference between the inverting and non-inverting inputs, according to the op-amp's configuration (closed-loop gain). 4 Input A Non-inverting input. This is the non-inverting terminal of the operational amplifier. The input signal applied here is amplified and appears at the output in-phase with the input. 5 V- Negative power supply input. This is the negative voltage supply pin for the operational amplifier. Typically ranges from -2.7V to -36V or 0V (single supply).Pin Function Details
V+ (Pin 1): This is the positive supply pin. It provides the necessary power for the operational amplifier to function. The OPA2376 operates on both single and dual supply voltages, and this pin must be connected to a positive voltage source. The range is typically between +2.7V to +36V for dual supply configurations, or between +2.7V to +18V for a single supply.
Input B (Pin 2): This pin is the inverting input. The voltage signal applied to this terminal is inverted and amplified. For a typical configuration such as an inverting amplifier, this terminal would receive the input signal.
Output (Pin 3): The output pin reflects the difference between the voltages at the non-inverting input (Pin 4) and the inverting input (Pin 2). The output voltage is directly influenced by the gain of the circuit and the input voltages applied at the input pins.
Input A (Pin 4): This is the non-inverting input. When a signal is applied to this pin, it will be amplified and appear at the output in-phase with the input signal. In a non-inverting amplifier configuration, this would be the signal input.
V- (Pin 5): This pin is the negative supply pin. Similar to the V+ pin, this provides the necessary power for the operational amplifier. It must be connected to a negative voltage source in dual supply configurations. For single supply configurations, this pin is typically tied to ground (0V).
