MSPS, 14-bit choices limited pipelined architectures that invariably mean high power. Until now, true 14-bit ADCs with simply exist. AD748x 14-bit ADCs that throughput rates high MSPS while consuming less than power.
These high speed, power, successive-approximation ADCs. AD7485 14-bit that features serial interface with throughput rates MSPS. 14-bit AD7484 12-bit AD7482 employ parallel interface modes that operate MSPS. These ADCs contain noise, wide-bandwidth track-andhold amplifier that handle input frequencies MHz. AD7485, AD7484, AD7482 exhibit excellent performance specifications. Thanks advanced design techniques, these parts achieve very power dissipation (~80 high throughput rates. There power-saving modes: mode consuming keeping reference circuitry active quick power-up, STANDBY mode that reduces power consumption These ADCs feature on-board reference also accommodate externally provided reference source. Also provided overrange capability 15th bit, analog input range strays outside nominal, which includes below ground, user still accurately resolve signal.
