GENERAL DESCRIPTION

The AD7273/AD7274 are 10-bit and 12-bit, high speed, low power, successive-approximation ADCs respectively. The parts operate from a single 2.35V to 3.6 V power supply and feature throughput rates up to 3 MSPS. The parts contain a low-noise, wide bandwidth track/hold amplifier which can handle input frequencies in excess of TBD MHz.

The AD7273/AD7274 use advanced design techniques to achieve very low power dissipation at high throughput rates.

The reference for the parts is applied externally and can be in the range of 1.2V to VDD. This allows the widest dynamic input range to the ADC.
