TLV990-21PFB is an analog front-end (AFE) which combines integrated analog electronics and microelectronics to provide high performance differentiated signal measurement capabilities. The AFE is designed for use in data acquisition applications, providing an interface between the physical world, an instrument or sensor, and the digital world, a computer or other digital system. It can be used to measure the differentiable parameters of physical systems, such as current, voltage, temperature, pressure, strain, and power. The TLV990-21PFB provides a wide range of differentiable signals that can be measured, including amplitude-modulated, frequency-modulated and differential signals.

The TLV990-21PFB is a complete Analog Front End (AFE) including analog and digital components. It is designed to be used in data acquisition applications, providing an interface between the physical sensing of a sample and the digital output.

The AFE consists of four major sections: the sensor inputs, analog signal conditioning, analog-to-digital converter, and digital logic.

The sensor inputs of the AFE consists of two full-range differential inputs and two additional differential input channels. The full-range differential inputs can be used to measure differentiable signals with a high resolution, while the additional input channels are used to measure lower resolution signals. The full-range differential inputs have a bipolar input range, which can be programmed to accommodate different input signals. The input conditioning circuitry of the AFE filters out noise from the signal and ensures that the signal sent to the analog-to-digital converter (ADC) is noise and distortion free.

The ADC of the AFE is an analog-to-digital conversion (ADC) module. It converts an analog input signal into a digital output. This unit offers high resolution, accuracy and dynamic range. It supports resolution of up to 16-bits and sampling rates up to 560 kSPS, depending on the type of signal being measured. The ADC supports both differential and single ended signals. The output of the ADC is typically sent to a digital processor, such as a field-programmable gate array (FPGA).

The digital logic components of the AFE are responsible for controlling the ADC and other parts of the system. The digital logic components provide the necessary signal processing and signal management, such as input gain and offset adjustment, triggering and time stamping of the signal data. They also provide the necessary communication interface to send the data to a digital processor, such as an FPGA or a computer.

The TLV990-21PFB offers important features for data acquisition applications, such as low power dissipation, high linearity and low distortion, high sampling rate and wide dynamic range.

The TLV990-21PFB can be used to measure a range of physical parameters, such as temperature, pressure, strain, current, voltage and power. It is designed for use in test and measurement and industrial applications. The AFE is designed for use in a wide range of environments, including high vibration and shock, temperature, humidity and pressure changes. This makes it suitable for use in a variety of industrial and laboratory applications.

In summary, the TLV990-21PFB analog front end (AFE) provides high performance differentiable signal measurement capabilities. It is designed for use in data acquisition applications and can be used to measure a wide range of differentiable physical parameters. The AFE offers important features such as low power dissipation, high linearity, wide dynamic range and high sampling rate and is suitable for use in a variety of environments.
