DESCRIPTION
The LTC
®
2365/LTC2366 are 1Msps/3Msps, 12-bit, sam-
pling A/D converters that draw only 2mA and 2.6mA, re-
spectively, from a single 3V supply. These high performance
devices include a high dynamic range sample-and-hold
and a high speed serial interface. The full scale input is
0V to V
DD
or V
REF
. Outstanding AC performance includes
72dB SINAD and –80dB THD at sample rates of 3Msps.
The serial interface provides flexible power management
and allows maximum power efficiency at low throughput
rates. These devices are available in tiny 6- and 8-lead
TSOT-23 packages.
The serial interface, tiny TSOT-23 package and extremely
high sample rate-to-power ratio make the LTC2365/LTC2366
ideal for compact, low power, high speed 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.
