The LTC6102 is an ultraprecise current sense amplifier that dramatically enhances efficiency and dynamic range. It features an input error as low as 10μV, enabling a measurement dynamic range of 16 bits while reducing power dissipation in the sense resistor.
This document is a design note (DN423) focusing on the LTC6102, an ultraprecise current sense amplifier with an input offset voltage of 10µV. The text explains how this precision allows for significantly reduced sense resistor values compared to typical amplifiers, thereby improving efficiency and dynamic range in electronic systems.
The device supports supply voltages ranging from 4V to 100V.
The amplifier typically draws a quiescent supply current of 300uA.
This amplifier reduces input error to a miniscule 10uV.
