3.5Msps Conversion Rate

74.1dB SINAD at 14-Bits, 71.1dB SINAD at 12-Bits  
Low Power Dissipation: 18mW  
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 13µW. The com-  
bination of speed, low power and tiny package makes the  
LTC2356-12/LTC2356-14suitableforhighspeed,portable  
applications.

Data Acquisition Systems  
Theserialinterfacesendsouttheconversionresultsduring  
the 16 clock cycles following a CONV rising edge for com-  
patibility 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.
