Working Principle:

The EL5323CL-T13 features an input stage consisting of two differential amplifiers, which amplifies the differential signal received from the external sources. The differential amplifiers are followed by a summing amplifier, which amplifies the differential voltage between the differential amplifiers. The summing amplifier can be programmed with gain resistors Rg1 and Rg2, to adjust the gain of the amplifier. The output stage consists of an operational amplifier, which amplifies the differential output from the summing amplifier. It also acts as a buffer, to isolate the load from the amplifier and prevent the feed-through from the load. The output from the operational amplifier is then buffered by the output buffer amplifier, which boosts the output current and provides the required output current level.

The summing and operational amplifiers are both connected to the power supply, to provide the required operating voltage. The summing amplifier is configured to operate in single supply mode, while the operational amplifier is configured to operate in dual supply mode. This helps reduce the power consumption, while providing the necessary performance.

The EL5323CL-T13 is highly accurate and offers low noise performance, high common-mode rejection ratio and wide dynamic range. These features, along with its low input bias current, fast settling time and low power consumption make it the ideal choice for medical, industrial and consumer electronics applications.
