LTC1407-1/LTC1407A-1

Serial 12-Bit/14-Bit, 3Msps

Simultaneous Sampling

ADCs with Shutdown

DESCRIPTION

FEATURES

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

makestheLTC1407-1/LTC1407A-1suitableforhighspeed,

portable applications.
