The LTC2313-14 is a 14-bit, 2.5Msps, serial sampling A/D converter that draws only 5mA from a single 3V or 5V supply. The LTC2313-14 contains an integrated low drift reference and reference buffer providing a low cost, high performance (20ppm/°C maximum) and space saving solution. The LTC2313-14 achieves outstanding AC performance of 77dB SINAD and –85dB THD while sampling at 2.5Msps. The extremely high sample rate-topower ratio makes the LTC2313-14 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 LTC2313-14 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3V and 5V logic. The fast 2.5Msps throughput with no cycle latency makes the LTC2313-14 ideally suited for a wide variety of high speed applications.
