Data acquisition is necessary to transform physical parameters, such as temperature, pressure, etc., into electrical signals, which then can be processed for further analysis. Analog front end (AFE) is a data acquisition device that is used for this purpose. AFE includes a variety of components for signal conditioning, such as voltage and current amplifiers, analog-to-digital (A/D) converters and filters. The XR10910IL40-F is a special variation of AFE, specifically designed for high speed, high resolution data acquisition applications.

The XR10910IL40-F delivers state-of-the-art performance with the highest resolution and accuracy. It can operate at speeds of up to 20Ms/s, with an input voltage range of 3.2V in single-ended mode and 6V in differential mode. The external reference voltage (VREF) can be adjusted between 3.2 and 5.5V. It also features four analog input channels and four analog output channels.

The XR10910IL40-F features sample-and-hold (S/H) circuit with a maximum input capacitance of 3.3pF and an input sample rate of up to 500Ks/s. It also offers a buffer amplifier with dynamic range of 6Vpp and a programmable filter (7th order Butterworth, fixed frequency band-pass) for signal rejection. Additionally, the device includes an onboard voltage reference, an output amplifier, a serial-to-analog converter (S/A) for generating analog output signals, and a digital-to-analog converter (D/A) for generating reference signals.

The XR10910IL40-F has many applications such as medical imaging, smart energy, automotive, and process control. For example, the device can be used to acquire continuous ECG or blood pressure signals in medical imaging systems, monitor and control power consumption in smart energy systems, detect pressure variations in automotive systems, or monitor process variables in process control systems.

The XR10910IL40-F AFE has two working modes: the first mode is the single-ended mode, in which all the input channels are connected to a single reference voltage, typically ground. In this mode, the output amplifiers are also connected to ground. The second mode is the differential mode, in which each input channel is connected to a pair of different reference voltages. In this mode, the output amplifiers can be connected to any of the reference voltages, allowing for greater flexibility.

The XR10910IL40-F typically requires the application of an external signal conditioning circuit to ensure a high input accuracy. Depending on the signal to be acquired, this circuit could include, for example, an amplifier, signal filter, signal rectifier, etc. Additionally, a high precision voltage reference is required for signal conversions as it is used for A/D and D/A reference voltage.

The XR10910IL40-F, which belongs to Data Acquisition - Analog Front End (AFE) family, is a powerful device designed for high speed, high resolution data acquisition applications, thanks to its features and capabilities, such as sample-and-hold (S/H) circuit, buffer amplifier, programmable filter, onboard reference voltage, output amplifiers, and A/D and D/A converters. The device provides superior performance, accuracy and resolution for a wide range of applications, such as medical imaging, smart energy, automotive, and process control.
