LTC2365/LTC2366
1Msps/3Msps, 12-Bit Serial
Sampling ADCs in TSOT
Features
Description
The LTC®2365/LTC2366 are 1Msps/3Msps, 12-bit,
sampling A/D converters that draw only 2mA and 2.6mA,
respectively, from a single 3V supply. These high perfor-
mance devices include a high dynamic range sample-and-
hold and a high speed serial interface. The full-scale input

Communication Systems
The high impedance single-ended analog input and the
ability to operate with reduced spans (down to 1.4V full
scale) allow direct connection to sensors and transducers
in many applications, eliminating the need for gain stages.
