LTC2365/LTC2366 1Msps/3Msps, 12-Bit Serial Sampling ADCs in TSOT Features Description n 12-Bit Resolution The LTC 2365/LTC2366 are 1Msps/3Msps, 12-bit, n 1Msps/3Msps Sampling Rates sampling A/D converters that draw only 2mA and 2.6mA, n Low Noise: 73dB SNR respectively, from a single 3V supply. These high perfor- n Low Power Dissipation: 6mW mance devices include a high dynamic range sample-and- n Single Supply 2.35V to 3.6V Operation hold and a high speed serial interface. The full-scale input n No Data Latency is 0V to V or V . Outstanding AC performance includes DD REF n Sleep Mode with 0.1A Typical Supply Current 72dB SINAD and 80dB THD at sample rates of 3Msps. n Dedicated External Reference (TSOT23-8) The serial interface provides flexible power management n 1V to 3.6V Digital Output Supply (TSOT23-8) and allows maximum power efficiency at low throughput n SPI/MICROWIRE Compatible Serial I/O rates. These devices are available in tiny 6- and 8-lead n Guaranteed Operation from 40C to 125C TSOT-23 packages. n 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/ a LTC2366 ideal for compact, low power, high speed systems. n Communication Systems The high impedance single-ended analog input and the n Data Acquisition Systems ability to operate with reduced spans (down to 1.4V full n Handheld Terminal Interface scale) allow direct connection to sensors and transducers n Medical Imaging in many applications, eliminating the need for gain stages. n Uninterrupted Power Supplies L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and n Battery-Operated Systems SoftSpan is a trademark of Linear Technology Corporation.
