The LTC2312-12 is a 12-bit, 500ksps, serial sampling A/D converter that draws only 3mA 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 72.7dB SINAD and –84dB THD while sampling at 500ksps. 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. The LTC2312-12 has a high speed SPI-compatible 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.
