ADCs with Shutdown
DESCRIPTIO
The LTC
®
1407/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 elimi-
nate ground loops and common mode noise by measuring
signals differentially from the source.
The devices convert 0V to 2.5V unipolar inputs differen-
tially. 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.
