Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

LT1399IGN#TRPBF is a family of precision, low power monolithic integrated circuit operational amplifiers which can be widely used in a variety of instrumentation and industrial applications, especially for applications which require low power consumption and low noise. By optimizing gain and offset errors as well as output noises and quiescent currents, it is possible to balance reasonable power consumption, low noise and high precision.

Application Field and Working Principle

Application Field

The LT1399IGN#TRPBF has a wide range of application fields, such as transducer interface, medical instrument, battery operated consumer products, medical and audio instruments, auto-level controls, voltage to current convertor and so on. These devices are especially suitable for precision analog circuits with high performance, low power consumption and low noise.

Working Principle

LT1399IGN#TRPBF consists of three parts: Operational Amplifier (op-amp), Open Loop Gain (AOL) and two feedback ciruits. The op-amp provides the basic non-inverting gain and inverting gain, while the AOL\'s function is to provide additional large-signal gain and to guarantee the stability of the device. The two feedback circuits are Rf and Ri respectively. The feedback resistance Rf is connected with the inverting input terminal and the Rf can affect the gain of the device. Ri is usually connected with the output and the Ri can limit the output current of the device. With the signal input, the differential signal is amplified by the op-amp and AOL, and then the signal is adjusted according to the ratio of Rf/Ri, finally the signal is sent to the output terminal.
