OPA376AIDBVR: Pin Function Specifications and Circuit Principles
Packaging Details: The OPA376AIDBVR is packaged in a SOT-23-5 package, which features 5 pins. Pin Function Table: Pin Number Pin Name Description and Function Usage and Notes 1 V+ Positive Power Supply This pin connects to the positive supply voltage. Typically, it is connected to a voltage source between +2.7V and +5.5V. 2 V– Negative Power Supply This pin connects to the negative supply, usually ground (0V). 3 IN+ Non-Inverting Input This is the non-inverting input terminal of the operational amplifier. It is used for the signal that will be amplified. 4 IN– Inverting Input This is the inverting input terminal of the operational amplifier. It is typically connected to a feedback network or reference voltage. 5 OUT Output This pin is the output of the operational amplifier. It provides the amplified signal. Circuit Principle:The OPA376AIDBVR is a precision, low-offset, rail-to-rail input/output operational amplifier. It works by amplifying the differential voltage between the non-inverting (IN+) and inverting (IN-) inputs and outputting the amplified signal on the OUT pin. The device requires a single or dual power supply connected to the V+ and V- pins.
V+ (positive supply) and V- (negative supply) set the operational voltage range for the op-amp. The IN+ and IN- pins are the two inputs that define the voltage difference that the amplifier amplifies. The OUT pin produces the amplified output signal corresponding to the difference in the input voltages. 20 Frequently Asked Questions (FAQ): What is the OPA376AIDBVR operational amplifier used for?
