Analog Devices Inc.The LTC2356-12/LTC2356-14 are 12-bit/14-bit, 3.5Msps serial ADCs with differential inputs. The devices draw only 5.5mA from a single 3.3V supply and come in a tiny 10-lead MSOP package. A Sleep shutdown feature further reduces power consumption to 13?W. The combination of speed, low power and tiny package makes the LTC2356-12/LTC2356-14 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 ?1.25V to 1.25V bipolar 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 a CONV rising edge for compatibility with standard serial interfaces. If two additional clock cycles for acquisition time are allowed after the data stream in between conversions, the full sampling rate of 3.5Msps can be achieved with a 63MHz clock.
