FEATURES

LTC1407-1/LTC1407A-1

Serial 12-Bit/14-Bit, 3Msps

Simultaneous Sampling

ADCs with Shutdown

DESCRIPTION

The LTC

1407-1/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.
