2. Pin Function Description Pin Number Pin Name Pin Type Description 1 V- Power Supply Negative power supply input. Connect to ground or a negative supply voltage. 2 In- Input Inverting input of the comparator. Signal is compared to the non-inverting input. 3 Out Output Output of the comparator. This pin provides the output signal, typically a logic level signal (high or low) based on the input comparison. 4 In+ Input Non-inverting input of the comparator. Signals here are compared to the inverting input. 5 V+ Power Supply Positive power supply input. Connect to a positive supply voltage (e.g., +5V). 3. Circuit Principle OverviewThe TLV3201AIDBVR is a single comparator IC. A comparator is a device that compares two input voltages and outputs a signal that indicates which input is higher. The IC has two input pins (In+ and In-) for receiving the signals to be compared. The output pin will be driven to either the positive supply (V+) or the negative supply (V-) depending on the result of the comparison. The behavior of this comparator is highly dependent on the relationship between the input signals:
If In+ is higher than In-, the output (Out) will be driven high (V+). If In- is higher than In+, the output (Out) will be driven low (V-).This part is typically used in applications where a threshold voltage needs to be detected, such as in zero-crossing detectors, analog-to-digital converters (ADCs), and other signal conditioning applications.
