1. Model: OPA364IDBVR
Brand: Texas Instruments Package Type: SOT-23 (Small Outline Transistor) Pin Count: 5 Functionality: Low-power precision operational amplifier Supply Voltage: ±2.5V to ±5.5V Output Drive Capability: Rail-to-rail output Package Dimensions: 2.9mm x 1.6mm2. Pinout for OPA364IDBVR (5-pin SOT-23 Package):
Pin Number Pin Name Function Description 1 V- (Pin 1) Negative Supply Voltage: This is the negative rail for the op-amp. It should be connected to ground in single-supply configurations or to the negative voltage in a dual-supply configuration. 2 In+ (Pin 2) Non-Inverting Input: This is the positive input of the operational amplifier, where the input signal is applied. 3 Output (Pin 3) Output: The output of the op-amp that provides the amplified signal. 4 In- (Pin 4) Inverting Input: This is the negative input of the operational amplifier, where the input signal is applied for inverted signal processing. 5 V+ (Pin 5) Positive Supply Voltage: This is the positive rail for the op-amp, connected to the positive supply voltage.3. Detailed Pin Function Specifications and Circuit Principle:
V- (Pin 1): The negative supply voltage pin, providing the lower potential for the op-amp. When used in a single-supply configuration, V- should be connected to ground (0V). In a dual-supply system, V- is connected to the negative supply rail (e.g., -5V in a ±5V configuration).
In+ (Pin 2): This is the non-inverting input. Signals applied here will be amplified in-phase by the op-amp. The voltage at the non-inverting input relative to the V- pin is the voltage that will be amplified and output through the Output pin.
Output (Pin 3): The output pin provides the amplified signal. It is a rail-to-rail output, meaning it can swing close to the supply rails (V+ and V-) under no load conditions, allowing the op-amp to provide a maximum output swing in single-supply or dual-supply operation.
In- (Pin 4): This is the inverting input of the op-amp. Signals applied here will be amplified but with an inverted polarity relative to the input signal at In+. A typical operational amplifier circuit will have feedback from the output to the inverting input to control the gain.
V+ (Pin 5): The positive supply voltage pin. This pin is connected to the positive rail in dual-supply configurations (e.g., +5V in a ±5V system) or to the positive supply voltage in single-supply configurations.
