The LT1679IS#TRPBF features an input offset voltage of 5mV, input bias current of 4pA max, full-scale gain of 1000V/V, and a high slew rate of 8V/us. Its low power consumption of 50uW during operation makes it an ideal choice for battery operated applications. Its high ESD immunity of 10000V provides additional protection against transient events. The LT1679IS#TRPBF also offers an extended temperature range from - 40°C to + 125°C.

The working principle of the LT1679IS#TRPBF is based on the commonly used three-stage op amp circuit. The first stage is the differential amplifier and is made up of two p-channel and n-channel MOSFETS, each consisting of a load resistor, gate and source connections. The second stage is the current amplifier, which is composed of a p- and n-channel MOSFETS operated in a differential configuration. The output stage is a unity-gain voltage amplifier which provides rail-to-rail output swings. The op amp’s performance is determined by the parameters of the individual stages, such as output current, capacitance, and input impedance.
