The LTC®1403/LTC1403A are 12-bit/14-bit, 2.8Msps serial ADCs with 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 LTC1403/LTC1403A suitable for high speed, portable applications.

The 80dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.

The LTC1403/LTC1403A convert 0V to 2.5V unipolar inputs differentially. The absolute voltage swing for +AIN and AIN extends from ground to the supply voltage.
