Package Type:
The TLV9001IDBVR comes in a SOT-23-5 package, which means it is a small, surface-mount device with 5 pins.
Pin Functions and Descriptions:
The following is a detailed explanation of the 5 pins and their respective functions for the TLV9001IDBVR operational amplifier:
Pin Number Pin Name Function Description 1 V- Negative power supply voltage. This pin should be connected to the negative side of the power supply (often ground in single-supply applications). 2 Inverting Input This pin receives the input signal that will be inverted in the output. The operational amplifier amplifies the voltage difference between the non-inverting input (Pin 3) and the inverting input (Pin 2). 3 Non-inverting Input This pin receives the input signal that will be amplified. The signal here is not inverted. 4 Output This pin provides the amplified output signal. The voltage here will be proportional to the difference between the signals at the inverting and non-inverting inputs, with gain applied. 5 V+ Positive power supply voltage. This pin should be connected to the positive side of the power supply.Circuit Principle:
The TLV9001 is a single-supply, low-power operational amplifier designed to function with a single voltage source (positive V+ and negative V-), but it can also work in dual-supply systems. The basic principle of operation is the amplification of the voltage difference between the inverting and non-inverting input pins, with the output pin reflecting the amplified result. It is typically used in configurations like inverting amplifiers, non-inverting amplifiers, or voltage followers, depending on the external circuit.

What is the maximum output current of the TLV9001IDBVR? The maximum output current of the TLV9001IDBVR is approximately 40 mA, which limits the amount of current that can be sourced or sunk by the output pin.
What are the key benefits of the TLV9001IDBVR? The TLV9001IDBVR offers low power consumption, small package size, and is optimized for precision applications, making it suitable for battery-operated devices and low-power circuits.
What is the input common-mode voltage range of the TLV9001IDBVR? The input common-mode voltage range of the TLV9001IDBVR extends from 0V to V+ - 1.5V, which means the input signal can be within this range to ensure proper operation.
How should the TLV9001IDBVR be used in an inverting amplifier configuration? To use the TLV9001IDBVR as an inverting amplifier, connect the input signal to the inverting input (Pin 2), and use a feedback resistor between the output (Pin 4) and the inverting input (Pin 2). The non-inverting input (Pin 3) should be grounded.
Can the TLV9001IDBVR be used in a voltage follower configuration? Yes, the TLV9001IDBVR can be used as a voltage follower by connecting the output (Pin 4) directly to the non-inverting input (Pin 3) and applying the input signal to the non-inverting input.
What is the output drive capability of the TLV9001IDBVR? The TLV9001IDBVR can drive standard resistive loads (typically up to 10kΩ) with low distortion and low power consumption, but it is not suitable for high-current or high-capacitance loads.
Is there any special consideration for PCB layout when using the TLV9001IDBVR? For optimal performance, it is important to keep the feedback path as short as possible, minimize noise coupling, and provide adequate decoupling capacitor s close to the power supply pins (Pins 1 and 5).
What are the thermal shutdown characteristics of the TLV9001IDBVR? The TLV9001IDBVR features internal thermal protection to prevent overheating, but it is not designed for high-power dissipation. Make sure the operating conditions remain within specified limits to avoid thermal shutdown.
What is the output impedance of the TLV9001IDBVR? The output impedance is typically low, around 50 Ω, under normal operating conditions. However, this can vary depending on the output voltage and current.
Can the TLV9001IDBVR be used in a differential amplifier configuration? Yes, the TLV9001IDBVR can be configured as a differential amplifier by appropriately connecting the inputs and feedback network to amplify the difference between two input signals.
How sensitive is the TLV9001IDBVR to electrostatic discharge (ESD)? The TLV9001IDBVR has built-in ESD protection on all pins to protect it from typical electrostatic discharge events, but care should still be taken during handling and assembly.
