Data acquisition signals can include electrical, sensing and temperature inputs; these must be converted, conditioned and amplified in order comprehend accurately. The Analog Front End (AFE) is the interface between the signal and the acquisition device whose role is to filter, buffer and amplify the signal, prepare it for conversion and effectively identify the various noise levels. An important element of the AFE is the instrumentation amplifier. The VSP2582RHNG4 is a monolithic, wideband, dynamically programmable two-channel instrumentation amplifier which is ideal for analog front end applications.

The VSP2582RHNG4 has two channels each with a dynamic range of between -6dB and +6dB extending to DC, with unity gain (>1kΩ) ensuring virtually noiseless operation. Its flexible signal conditioning options and high accuracy measurement capability makes it suitable for medical and industrial signal processing applications including accelerometers, pressure sensors, weighing systems and fluid flow. The components and settings of the device can be changed after fabrication, an important feature of the design.

The VSP2582RHNG4 employs a versatile circuit design which allow the user to control parameters such as gain, bandwidth and power consumption. Each channel also offers tunable ESD protection with contact discharge ratings up to 16kV, making it suitable for even the most demanding environmental applications. The VSP2582RHNG4 also offers a wide range of safety and diagnostics protections. It integrates a high accuracy temperature sensor to monitor the temperature of the application and enable the user to identify and react to any excessive heating conditions.

The VSP2582RHNG4 is designed to drive high capacitive loads of up to 2 hundreds of pico Farad and offers its users an adjustable input impedance for improved noise filtering capabilities. The user is also able to choose from various input configurations such as single-ended or differential-sided. This flexibility allows the user to optimize the VSP2582RHNG4 to match the noise levels of their input signals.

The VSP2582RHNG4 offers up to 4 amplifier settings that are programmable on each channel. All settings are accessible via its user-friendly graphical user interface (GUI) or via its USB port. The amplified signal is output through a digital to analog convertor (DAC) which can be configured for either standard-resolution or 4-bit input for higher resolution. The VSP2582RHNG4 can also be configured to operate in single ended mode, providing the user with additional setup flexibility and control.

The VSP2582RHNG4 offers great range, accuracy, and flexibility in its capabilities making it suitable for a range of data acquisition applications. Its adjustable input impedance, programmability, and integrated temperature sensor ensure that the analog front end remains optimised at all times. By optimising the gain and bandwidth, users can ensure that the right amount of data is received with the right accuracy and within the right time frame. The VSP2582RHNG4 is an invaluable addition to any data acquisition system and its range of features ensures that it delivers reliable and precise data at all times.
