The LTC1407-1/LTC1407A-1 contain two separate differential inputs that are sampled simultaneously on the rising edge of the CONV signal. These two sampled inputs are then converted at a rate of 1.5Msps per channel. The 80dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The devices convert 1.25V to 1.25V bipolar inputs differentially. The absolute voltage swing for CH0+, CH0, CH1+ and CH1 extends from ground to the supply voltage.
