LTC2365 - 1Msps, 12-Bit Serial Sampling ADCs in TSOT

The LTC®2365/LTC2366 are 1Msps/3Msps, 12-bit, sampling A/D converters that draw only 2mA and 2.6mA, respectively, from a single 3V supply. These high performance devices include a high dynamic range sample-andhold and a high speed serial interface. The full-scale input is 0V to VDD or VREF. 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.
