LTC2312ITS8-14#TRMPBF

LTC®2312-14 is a 14bit, 500ksps serial sampling ADC that draws only 3.2mA from a single 3Vor 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. The fast 500ksps throughput with no-cycle latency makes the device ideally suited for a wide variety of high speed applications. Application includes communication Systems, high speed data acquisition, handheld terminal interface, medical imaging, uninterrupted power supplies, battery operated systems, automotive.
