The LTC2351CUH-14#PBF is a 6-channel 14-bit simultaneous sampling Analog-to-digital Converter (ADC) shutdown and 6 simultaneously sampled differential inputs. A sleep shutdown mode further reduces power consumption to 12μW. These six sampled inputs are then converted at a rate of 250ksps per channel. The 83dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The device converts 0 to 2.5V unipolar inputs differentially or ±1.25V bipolar inputs also differentially, depending on the state of the BIP pin. Any analog input may swing rail-to-rail as long as the differential input range is maintained. The conversion sequence can be abbreviated to convert fewer than six channels, depending on the logic state of the SEL2, SEL1 and SEL0 inputs. The serial interface sends out the six conversion results in 96 clocks for compatibility with standard serial interfaces.
