Description

The LTC®1407-1/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 10mW. 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 LTC1407-1/LTC1407A-1 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 compatibility with standard serial interfaces.
