Linear Technology’s LTC6103 contains two independent, high side current sense amplifiers. The topology allows the second amplifier to be used for bi-directional operation, high/low current ranging or high voltage level translation. The LTC6103 features: input bias current is 170nA Max and the maximum input offset voltage is 450µV.

The LTC6103 can withstand voltages up to 70V and has a response time of 1µsec. Gain for each device is set by two resistors and since the gain resistors are the primary determinants of accuracy, precision resistors allow for accuracy better than 1%.
