Description

The LTC2314-14 is a 14-bit, 4.5Msps, serial sampling A/D converter that draws only 6.2mA from a wide range analog supply adjustable from 2.7V to 5.25V. The LTC2314-14 contains an integrated bandgap and reference buffer which provide a low cost, high performance (20ppm/°C max) and space saving applications solution. The LTC2314-14 achieves outstanding AC performance of 77dB SINAD and –85dB THD while sampling a 500kHz 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 1.8V, 2.5V, 3V and 5V logic. The fast 4.5Msps throughput makes the LTC2314-14 ideally suited for a wide variety of high speed applications.ApplicationsCommunication SystemsHigh Speed Data AcquisitionHandheld Terminal InterfaceMedical ImagingUninterrupted Power SuppliesBattery Operated SystemsAutomotive
