LTC2312HTS8-12#TRMPBF

LTC2312HTS8-12#TRMPBF is a 12-bit, 500ksps, serial sampling A/D converter that draws only 3mA 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. 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. Application includes communication systems, high speed data acquisition, handheld terminal interface, medical imaging, uninterrupted power supplies, battery operated systems, automotive.
