Linear Technology's LTC2314-14 is a 14-bit, 4.5 MSPS, serial sampling A/D converter that draws only 6.2 mA from a wide-range analog supply, adjustable from 2.7 V to 5.25 V. The LTC2314-14 contains an integrated band-gap and reference buffer, which provides a low cost, high performance (20 ppm/°C max), space-saving applications solution. The LTC2314-14 achieves outstanding AC performance of 77 dB SINAD and -85 dB THD while sampling a 500 kHz input frequency. The extremely high sample, rate-to-power ratio makes the LTC2314-14 ideal for compact, low power, high-speed systems. The LTC2314-14 also provides both nap and sleep modes for further optimization of the device power within a system.
The LTC2314-14 has a high-speed, SPI-compatible serial interface that supports 1.8 V, 2.5 V, 3 V, and 5 V logic. The fast 4.5 Msps throughput makes the LTC2314-14 ideally suited for a wide variety of high-speed applications.
