LTC2312ITS8-12#TRMPBF

LTC®2312-12 is a 12bit, 500Ksps, serial sampling A/D converter. This 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 LTC2312-12 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. Application includes communication systems. high speed data acquisition, handheld terminal interface, medical imaging, uninterrupted power supplies, battery operated systems, automotive.
