vs Input Frequency
The LTC
2355-12/LTC2355-14 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 LTC2355-12/
LTC2355-14 suitable for high speed, portable applications.
The 80dB common mode rejection allows users to elimi-
nate ground loops and common mode noise by measuring
signals differentially from the source.
The devices convert 0V to 2.5V unipolar 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 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.
