Exam 14: Special-Purpose Integrated Circuits

The classic three- op- amp instrumentation amplifier will have a differential gain of 1 if RG is not connected.

Isolation amplifiers can isolate the input and output by

Figure 6 -Refer to Figure 6(a). The circuit is

An OTA is often used to isolate a sensitive input from high voltage.

The amount of bias current for an OTA changes the

An ISO124 isolation amplifier has an internal oscillator of 500 kHz. The oscillator signal

An excellent way to reduce leakage current on the input lines is to

A log amplifier is used for

An OTA has

Audio power amplifiers typically have a bandwidth from 3 kHz to 30 kHz.
