DESCRIPTION
Serial 12-Bit/14-Bit, 3Msps
Simultaneous Sampling
ADCs with Shutdown
The LTC1407-1/LTC1407A-1 are 12-bit/14-bit, 3Msps
ADCs with two 1.5Msps simultaneously sampled differ-
ential inputs. The devices draw only 4.7mA from a single
3V supply and come in a tiny 10-lead MS package. A sleep
shutdown feature lowers power consumption to 10μW.
The combination of speed, low power and tiny package
makes the LTC1407-1/LTC1407A-1 suitable for high speed,
portable applications.
The LTC1407-1/LTC1407A-1 contain two separate differ-
ential inputs that are sampled simultaneously on the rising
edge of the CONV signal. These two sampled inputs are
then converted at a rate of 1.5Msps per channel.
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 differ-
entially. The absolute voltage swing for CH0+, CH0–, CH1+
and CH1– extends from ground to the supply voltage.
The serial interface sends out the two conversion results in 32
clocks for compatibility with standard serial interfaces.
