The TLV9062IDR comes in a 5-pin package with the following pinout and function descriptions:
Pinout (5-pin SOT-23): Pin Number Pin Name Pin Function Description 1 Out A Output of Op-Amp A. This pin delivers the amplified output signal for channel A. 2 In A- Inverting input of Op-Amp A. The input signal is applied to this pin to be inverted. 3 V- Negative power supply pin. This is connected to the ground or the negative voltage rail of the power supply. 4 In A+ Non-inverting input of Op-Amp A. The input signal is applied to this pin to be amplified without inversion. 5 Out B Output of Op-Amp B. This pin delivers the amplified output signal for channel B.4. Function Descriptions:
Pin 1 (Out A): The output pin for the first op-amp (A) of the TLV9062. The amplified signal will appear here based on the input at the non-inverting or inverting input. Pin 2 (In A-): The inverting input for the first op-amp (A). Signals that are applied to this pin will be inverted in the output at pin 1. Pin 3 (V-): The negative power supply for the operational amplifier. Typically, this pin is connected to ground or the lowest voltage rail in the system. Pin 4 (In A+): The non-inverting input for the first op-amp (A). Signals applied to this pin will result in a non-inverted output at pin 1. Pin 5 (Out B): The output for the second op-amp (B). It works the same way as Pin 1 (Out A), but for the second op-amp in the package.5. Pin Function Usage:
The V- (Pin 3) is typically connected to the negative voltage rail or ground, depending on the system's requirements. The In A+ (Pin 4) and In A- (Pin 2) inputs can be connected to various signal sources (either differential or single-ended). The Out A (Pin 1) and Out B (Pin 5) outputs are the resulting amplified signals.6. Common Usage:
The TLV9062IDR is frequently used for low-power signal amplification tasks, including sensor interfacing, audio amplification, and filtering. It is often found in applications where space is limited due to the small 5-pin package, but high precision and low power are still required.7. FAQ (Frequently Asked Questions)
