LTC2361 - 250ksps, 12-Bit Serial ADCs in TSOT-23

The LTC2360/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 VDD or VREF. 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.
