8-Lead TSOT-23 Package 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 …
