Working Principle

The ISL28217FRTZ-T13 is a transconductance amplifier which acts as an integrator of a differential voltage. The differential voltage is applied to the input pins, and the output of the amplifier is proportional to the integrated voltage. This translates to a gain of 13.7 dB in the audio bandwidth. In addition, it offers excellent linearity, low noise, and low distortion.

The amplifier features a low-noise preamplifier and a low-level voltage gain stage for high input impedances and large signal gains. The cascoded differential amplifier provides a high-input impedance with low level of noise. The over-temperature shutdown feature further enhances the amplifier’s safety, as it shuts down the device to prevent damage if the internal temp rises above a set temperature.

Conclusion

The ISL28217FRTZ-T13 is an excellent choice for a wide range of applications that require a low distortion, low noise amplifier. It offers a wide supply voltage range and adjustable gain, making it well-suited for use in a variety of audio and instrumentation systems. The amplifier also features a thermal shutdown feature that prevents damage if the temperature rises above a set point.

The excellent linearity, low noise levels, and fast over-temperature shutdown delay make the ISL28217FRTZ-T13 an ideal choice for a variety of audio applications, including medical instruments, instrumentation, consumer products, automotive audio systems, and professional audio systems.
