ANALOG DEVICES LTC1403AIMSE#PBF Analogue to Digital Converter, SAR, 14 bit, 2.8 MSPS, 1 Channels, Differential, 3 Wire, Serial

LTC1403A is a serial ADC with differential inputs. The combination of speed, low power and tiny package makes the device 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 devices convert 0V to 2.5V unipolar inputs differentially. The absolute voltage swing for +AIN and -AIN extends from ground to the supply voltage. The serial interface sends out the conversion results during the 16 clock cycles following CONV↑ for compatibility with standard serial interfaces. It is widely used in application such as automotive, communications, data acquisition systems, uninterrupted power supplies, multiphase motor control, multiplexed data acquisition etc.
