LTC2314-14 14-Bit, 4.5Msps Serial Sampling ADC in TSOT DESCRIPTION The LTC®2314-14 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 ...
