This ensures long battery life.• High Gain: The XRD98L59AIG-F provides a system gain of up to 63 dB, which allows it to accurately measure low-level signals. • Small Size: The XRD98L59AIG-F is available in two package types, TQFP or PQFP. This makes it an ideal choice for applications requiring small space and weight. • On-Board Reference: The XRD98L59AIG-F features an on-board reference that eliminates the need for external positive and negative reference voltage signals. • Wide Input Range: The XRD98L59AIG-F supports inputs of up to 10V.

Applications

The XRD98L59AIG-F can be used in a variety of different applications, including: • Bridges: The XRD98L59AIG-F can be used to measure bridge inputs. • Temperature Measurement: The XRD98L59AIG-F can be used for temperature measurement via thermocouples.• Pressure Measurement: The XRD98L59AIG-F can be used to measure pressure from strain gages. • Force Measurement: The XRD98L59AIG-F can be used to measure force or torque sensors. • Patient Monitoring: The XRD98L59AIG-F can be used in patient monitoring applications such as MRI systems. • Automotive Applications: The XRD98L59AIG-F can also be used in automotive applications such as airbag control.

Working principle

The XRD98L59AIG-F utilizes a single supply design, where all parts of the circuit are powered by a single supply voltage, usually between 3V and 5V. It works by filtering and amplifying AC and DC components of input signals, and then converting them into digital form for subsequent processing by the microcontroller or DSP.The input of XRD98L59AIG-F consists of two channels, i.e. a differential or single-ended input, and a single-ended reference input. The analog signal is buffered and amplified by the fully differential instrumentation amplifier (INA). The amplified signal is then fed to a gain stage and then passed through a sample and hold circuit for further amplification. After this process, the digital signal is generated, which can be processed further by the microcontroller or DSP.

Conclusion

The XRD98L59AIG-F is an Analog Front End (AFE) device developed by Xilinx Corporation, suitable for data acquisition from temperature, pressure, force and torque sensors. It provides a high gain, low power, and small size solution for signal processing. Furthermore, the on-board reference eliminates the need for external referencing, making it an ideal choice for a wide range of applications including patient monitoring, airbag control, and robotic applications.
