Description
Serial 12-Bit/14-Bit, 2.8Msps
Sampling ADCs with Shutdown
The LT C
®
1403/LTC1403A are 12-bit/14-bit, 2.8Msps se-
rial ADCs with 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 LTC1403/LTC1403A
suitable for high speed, portable applications.
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 +A
IN
and –A
IN
extends from
ground to the supply voltage.
The serial interface sends out the conversion results during
the 16 clock cycles following CONV↑ for compatibility 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 2.8Msps
can be achieved with a 50.4MHz clock.
