LTC2360/LTC2361/LTC2362
100ksps/250ksps/500ksps,
12-Bit Serial ADCs in TSOT-23
DESCRIPTION
The LTC^®2360/LTC2361/LTC2362 are 100ksps/250ksps/
500ksps, 12-bit, sampling A/D converters that draw only
0.5mA, 0.75mA and 1.1mA, respectively, from a single
3V supply. The supply current drops at lower sampling
rates because these devices automatically power down
after conversions. The full-scale input of the LTC2360/
LTC2361/LTC2362 is 0V to V_DD or V_REF. These ADCs 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 LTC2360/
LTC2361/LTC2362 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.
