serial ADCs with differential inputs. The devices draw only  
5.5mAfromasingle3.3Vsupplyandcomeinatiny10-lead  
MSOP package. A Sleep shutdown feature further reduces  
power consumption to 13µW. The combination of speed,  
low power and tiny package makes the LTC2355-12/  
LTC2355-14 suitable for high speed, portable applications.

Theserialinterfacesendsouttheconversionresultsduring  
the 16 clock cycles following a CONV rising edge for  
compatibility with standard serial interfaces. If two addi-  
tional 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.
