The devices draw only 4.7mA from a single 3V supply and come in a tiny 10-lead MS package. A sleep shutdown feature lowers power consumption to 10μW. The combination 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 80dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The ...
