The LTC1407-1/LTC1407A-1 are 12-bit/14-bit, 3Msps ADCs with two 1.5Msps simultaneously sampled differential inputs. 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 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 32clocks for compatibility with standard serial interfaces.
