ISL28433FVZ Application Field and Working Principle

The ISL28433FVZ is a precision low power instrumentation amplifier (PGA) designed to accurately measure signals in a wide range of applications. The ISL28433FVZ is designed to give best-in-class performance, outstanding stability, and higher accuracy within a tiny 4mmx4mm thermal pad-free QFN package. With an internal gain range of 0.01V/V to 10V/V and adjustable temperature drift of 0.01V/V/°C over the -40° to +125°C temperature range, the ISL28433FVZ provides superior performance for industrial, medical and instrumentation applications.

The ISL28433FVZ operates from a single, +3V or +5V supply and draws only 400µA typical, making it ideal for size, weight and power (SWaP) constrained battery operated systems. And, with a ±2.7V to ±18V input common mode range, the ISL28433FVZ can easily measure signals in high EMI environments.

Application Field of ISL28433FVZ

The ISL28433FVZ is ideal for a variety of industrial and medical applications, such as:

• Industrial Process Control
• Medical Instrumentation and Monitoring
• Miniaturized Solutions
• Data Acquisition (DAQ)
• Test and Measurement

The high CMRR and PSRR performance of the ISL28433FVZ translates into outstanding noise rejection and low system power, making it suitable for use in even the most challenging applications. This PGA can measure ac signals up to 4kHz, allowing the user to measure both low frequency and high frequency signals with precision and confidence.

Working Principle of ISL28433FVZ

The ISL28433FVZ is a low-power, low-distortion PGA designed to meet the demands of industrial and medical applications. The device works by amplifying and buffering a differential input signal. The input signal is amplified by the PGA and then buffered by the amplifier designed specifically to drive the output stage of the PGA. The amplifier has a high CMRR of 60dB, which ensures superior noise-rejection performance. Additionally, the amplifier has a PSRR of 60dB at 1kHz, so the device is well-suited for applications in which the input signal is experiencing high levels of power supply noise.

The ISL28433FVZ also features excellent thermal drift performance, with a temperature drift of 0.01V/V/°C over the -40° to +125°C temperature range. This allows the PGA to operate reliably in extreme temperature environments, ensuring accuracy and repeatability in even the most challenging applications. The device is also capable of operating from a single 3V or 5V power supply, making it ideal for size and power constrained applications.

The combination of low power consumption, extended temperature ranges, and high CMRR, PSRR and temperature drift performance makes the ISL28433FVZ the ideal choice for industrial, medical and instrumentation applications.
