DESCRIPTION The LTC®2312-12 is a 12-bit, 500ksps, serial sampling A/D converter that draws only 3m A from a single 3V or 5V supply. The LTC2312-12 contains an integrated low drift reference and reference buffer providing a low cost, high performance (20ppm/°C maximum) and space saving solution. The LTC2312-12 achieves outstanding AC performance of 72.7d B SINAD and - 84d B THD while sampling at 500ksps. The extremely high sample rate-topower ratio makes the LTC2312-12 ideal for pact, low power, high speed systems. The supply current decreases at lower sampling rates as the device automatically enters nap mode after conversions. The LTC2312-12 has a high speed SPI-patible serial interface that supports 1.8V, 2.5V, 3V and 5V logic. The fast 500ksps throughput with no-cycle latency makes the LTC2312-12 ideally suited for a wide variety of high speed applications. plete 14-/12-Bit Pin-patible SAR ADC Family 500ksps 2.5Msps 4.5Msps 5Msps 14-Bit LTC2312-14 LTC2313-14 LTC2314-14 12-Bit LTC2312-12 LTC2313-12 LTC2315-12 Power 3V/5V 9m W/15m W 14m W/25m W 18m W/31m W 19m W/32m W TYPICAL APPLICATION 5V Supply,...
