Its low offset and high precision make it suitable for system-level control applications such as power metering, as well as sensor monitoring for medical imaging/measurement systems.Working Principle of LT6105HMS8#PBFThe LT6105HMS8#PBF is a differential amplifier operating from dual supplies of 5V and 13V. It has four amplification channels, each containing an input buffer, a single-stage differential amplifier, and an output buffer. The single-stage differential amplifier consists of a P-type differential transistor and a 1kΩ resistor to generate the gain of the amplifier, and a 3.5kΩ resistor to set the offset voltage. The gain and offset of the amplifier are set by connecting two external resistors to the pins marked as "GND" and "VIN".The output voltage of the amplifier is obtained by subtracting the output voltage of the P-type differential transistor from the input voltage. The gain of the amplifier is inversely proportional to the resistance of the two resistors. A higher value of resistance will result in a lower gain. The output voltage is also affected by the 3.5kΩ resistor that defines the offset voltage. The output voltage is proportional to the difference between the input voltage and the offset voltage.ConclusionIn conclusion, the LT6105HMS8#PBF from Linear Technology is a high-speed, high-precision instrumentation amplifier suitable for various performance demanding applications. It offers minimum offset voltage and low total harmonic distortion for precision analog-to-digital conversion. It offers maximum dynamic range and low noise with excellent common-mode rejection ratio.
