DESCRIPTION
Serial 12-Bit/14-Bit, 3.5Msps
Sampling ADCs with Shutdown
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 13W. The com-
bination of speed, low power and tiny package makes the
LTC2356-12/LTC2356-14suitableforhighspeed,portable
applications.
The80dBcommonmoderejectionallowsuserstoeliminate
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.
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.
