14-Bit, 500ksps Serial Sampling ADC in TSOT

The LTC2312-14 is a 14-bit, 500ksps, serial sampling A/D converter that draws only 3.2mA from a single 3V or 5V supply. The LTC2312-14 contains an integrated low drift reference and reference buffer providing a low cost, high performance (20ppm/°C maximum) and space saving solution. The LTC2312-14 achieves outstanding AC performance of 77dB SINAD and –85dB THD while sampling at 500ksps. The extremely high sample rate-to-power ratio makes the LTC2312-14 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 LTC2312-14 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 LTC2312-14 ideally suited for a wide variety of high speed applications.
