LTC1407/LTC1407A

Serial 12-Bit/14-Bit, 3Msps

Simultaneous Sampling

ADCs with Shutdown

FEATURES

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.

80dB Common Mode Rejection at 100kHz

0V to 2.5V Unipolar Input Range

Tiny 10-Lead MS Package

■

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-

nategroundloopsandcommonmodenoisebymeasuring

signals differentially from the source.

APPLICATIO S

■

Telecommunications

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.

Data Acquisition Systems

■

Uninterrupted Power Supplies

Multiphase Motor Control

I & Q Demodulation

Industrial Control

■

The serial interface sends out the two conversion results in

32 clocks for compatibility with standard serial interfaces.
