Analog Devices AD7356

The AD7356 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With 2.5 V supply and a 5 MSPS throughput rate, the part consumes 14 mA typically. The part also offers flexible power/throughput rate management when operating in normal mode as the quiescent current consumption is so low.

GENERAL DESCRIPTION

The AD73561 is a dual, 12-bit, high speed, low power, successive approximation ADC that operates from a single 2.5 V power supply and features throughput rates up to 5 MSPS. The part contains two ADCs, each preceded by a low noise, wide bandwidth track-andhold circuit that can handle input frequencies in excess of 200 MHz.
