Working Principle

The MAX479CSD is a voltage output, linear amplifier. It features a differential input stage with a very high common-mode range and very low distortion, making it ideal for data transduction and other applications that require wide signal swings and excellent linearity. The MAX479CSD has a low power dissipation of 1.3 mW/ amplifier and can be configured with a variety of external components to provide the signal conditioning needed for a specific application.

Its “gain” (transimpedance, voltage gain, or voltage-to-current gain) is set externally, with appropriate selection of the amplifier’s feedback components. The amplifier also has a low input offset voltage of 0.5 mV and is capable of settling quickly to 0.1 % over 1M load in 1 µs, to provide closely-timed, accurate measurements. Furthermore, the device is offered in an 8-pin SOT-23 package, making it an excellent choice for space-constrained applications.
