LINEAR TECHNOLOGY  LTC2351CUH-12#PBF  模数转换器, 12 bit, 1.5 MSPS, 单, 2.7 V, 3.6 V, QFN

The is a 12-bit Analog-to-digital Converter ADC with shutdown and 6 simultaneous sampled differential inputs. The device draws only 5.5mA from a single 3V supply. A sleep shutdown mode further reduces power consumption to 12µW. The 6 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 6-channel, 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.
