Working Principle

The LT2078IS8#TRPBF is an instrumentation amplifier that uses a differential-to-single-ended configuration with an output common-mode voltage that can be adjusted to meet the needs of different systems. The device consists of three amplifier stages. The first stage is an input differential amplifier, which conditions an input signal before passing it on to the second stage. In the second stage, a single-ended gain stage amplifies the signal. The third stage is the output differential amplifier, which takes the output of the gain stage and compares it to a reference voltage to adjust the common-mode voltage. The combined action of all three stages results in outstanding ac and dc performance.

Conclusion

The LT2078IS8#TRPBF is an ideal choice for a wide range of high precision amplifier applications due to its excellent ac and dc performance. Its wide voltage range (4V to 72V), differential input/output voltage range (up to 80V), low bias current (typical 8pA), low input offset voltage (<3mV), and high CMRR (100dB) make it an ideal choice for use in medical equipment, data acquisition systems, industrial process control, and voltage monitoring and power supply circuits. Its three-stage configuration ensures high voltage gain and low output impedance, providing excellent ac and dc performance. Its ability to operate from 2.6V makes it an ideal choice for portable devices.
