DESCRIPTION
Serial 12-Bit/14-Bit, 3Msps
Simultaneous Sampling
ADCs with Shutdown
The LTC1407/LTC1407A are 12-bit/14-bit, 3Msps ADCs
with two 1.5Msps simultaneously sampled differential
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/LTC1407A suitable for high speed,
portable applications.
The LTC1407/LTC1407A contain two separate differential
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 0V to 2.5V unipolar inputs differentially.
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.
