The devices draw only 4.7m A from a single 3V supply and e in a tiny 10-lead MS package. A sleep shutdown feature lowers power consumption to 10μW. The bination of speed, low power and tiny package makes the LTC1407-1/LTC1407A-1 suitable for high speed, portable applications. 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 80d B mon mode rejection allows users to eliminate ground loops and mon 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. The serial interface sends out the two conversion results in 32 clocks for patibility with standard serial interfaces.
