LT1399IS#TRPBF

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The LT1399IS#TRPBF or LT1399IS device is a tiny, high-performance operational amplifier (opamp) with a low input offset voltage of under 650 microvolts and an extremely low input bias current. The device has two differential inputs and two output stages. It is packaged in a small 4-pin SOT23 package. The LT1399IS#TRPBF is capable of driving up to 25mA into a load of 10kΩ from a 5V power supply.

Application Field

The LT1399IS#TRPBF devices can be used for a wide range of applications, such as audio signal conditioning, instrumentation, and data acquisition systems. It can also be used for small-signal switching or amplifying. The extremely low input bias current and offset voltage ensures that the LT1399IS#TRPBF’s performance is not affected by input voltage shifts.

Working Principle

The LT1399IS#TRPBF is based on a fully differential cascode topology. The device has two differential inputs and two output stages. The input stage of the amplifier is a single stage differential amplifier that provides both an adjustable bandwidth and extremely high input impedance. The output stage is also a single stage amplifier that provides an output of up to 25mA into a 10kΩ load from a 5V power supply.

The LT1399IS#TRPBF operational amplifier has a gain bandwidth of 2.5MHz, which is suitable for a wide range of applications. The device features an extremely low input bias current, which is great for situations where the input voltage needs to be very precise. The op-amp also offers an excellent noise performance of just 4nV/√Hz, which is perfect for applications that require low-noise performance.
