LTC2360/LTC2361/LTC2362 100ksps/250ksps/500ksps, 12-Bit Serial ADCs in TSOT-23 FEATURES DESCRIPTION n 12-Bit Resolution The LTC 2360/LTC2361/LTC2362 are 100ksps/250ksps/ n Low Noise: 73dB SNR 500ksps, 12-bit, sampling A/D converters that draw only n Low Power Dissipation: 1.5mW at 100ksps 0.5mA, 0.75mA and 1.1mA, respectively, from a single n 100ksps/250ksps/500ksps Sampling Rates 3V supply. The supply current drops at lower sampling n Single Supply 2.35V to 3.6V Operation rates because these devices automatically power down n No Data Latency after conversions. The full-scale input of the LTC2360/ n Sleep Mode with 0.1A Typical Supply Current LTC2361/LTC2362 is 0V to V or V . These ADCs are DD REF n Dedicated External Reference (TSOT23-8) available in tiny 6- and 8-lead TSOT-23 packages. n 1V to 3.6V Digital Output Supply (TSOT23-8) The serial interface, tiny TSOT-23 package and extremely n SPI/MICROWIRE Compatible Serial I/O high sample rate-to-power ratio make the LTC2360/ n Guaranteed Operation from 40C to 125C LTC2361/LTC2362 ideal for compact, low power, high n Tiny 6- and 8-Lead TSOT-23 Packages speed systems. APPLICATIONS The high impedance single-ended analog input and the ability to operate with reduced spans (down to 1.4V full n Communication Systems scale) allow direct connection to sensors and transducers in n Data Acquisition Systems many applications, eliminating the need for gain stages. n Handheld Portable Devices L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Uninterrupted Power Supplies Technology Corporation.
