LTC2312CTS8-14#TRMPBF

LTC2312CTS8-14#TRMPBF is a 14bit, 500ksps, serial sampling A/D converter that draws only 3.2mA from a single 3V or 5V supply. It contains an integrated low drift reference and reference buffer providing a low cost, high performance (20ppm/°C maximum) and space-saving solution. It achieves outstanding AC performance of 77dB SINAD and -85dB THD while sampling at 500ksps. The extremely high sample rate-to-power ratio makes the device ideal for compact, low-power high-speed systems. The supply current decreases at lower sampling rates as the device automatically enters nap mode after conversions. It has a high-speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3V and 5V logic. Applications include communication systems, high speed data acquisition, handheld terminal interface, medical imaging, uninterrupted power supplies, battery-operated systems, and automotive.
