Instrumentation, OP Amps, Buffer Amps

The LT1783IS5#TRMPBF is a low-cost, low-noise, rail-to-rail output instrumentation amplifier that has been developed to meet the highest technical performance standards for general purpose signal conditioning applications. It provides high common-mode rejection (CMRR) and excellent unipolar current sources at its inputs. The output is rail-to-rail, which allows for improved dynamic range utilization and minimized distortion. This device can be used in high-precision applications such as medical, communication, aerospace and industrial instrumentation.

The LT1783IS5#TRMPBF offers two high-sensitivity input channels, making it ideal for very low-level signals. Each channel features a wide input common-mode input range of 0.4V to 5V, a low traditional noise of 5nV/√Hz, a low-profile IC package, and a wide 0.8V to 16V operating voltage range. In addition, the LT1783IS5#TRMPBF has a wide output common-mode range that is ideal for monitoring remote environment.

The LT1783IS5#TRMPBF provides excellent unipolar current sources at its input. The two amplifiers’ gain is factory-trimmed to 1V/V or 2V/V, and rail-to-rail outputs are possible. The output range is independent of the supply voltage. The amplifier features precise AC and DC performance, low power consumption and excellent stability over temperature.

The instrumentation amplifier’s working principle involves the combination of multiple amplifier stages. The first amplifier stage is a differential amplifier, followed by a gain amplifier, and lastly a unity gain output stage. The input impedance of the LT1783IS5#TRMPBF is extremely high, and thus the input bias current is very low. The device also exhibits high common-mode rejection ratio (CMRR) which is very important for accurate AC measurements.

The LT1783IS5#TRMPBF can be used in a wide variety of applications where high common-mode rejection and low noise performance is required. These include strain gauge measurements, thermocouple measurements, communication interface circuitry, high resolution instrumentation, low-level DC measurements, etc. The amplifier is especially suitable for low-level signals, as the input current and noise is kept to a minimum.

In summary, the LT1783IS5#TRMPBF is a low-cost, low-noise, rail-to-rail output instrumentation amplifier that is designed to meet the highest technical performance standards. Its wide input common-mode range, low input bias and noise, and rail-to-rail outputs make it suitable for a wide range of applications, such as medical, communication, and aerospace instrumentation.
