AD7495ARZ

模数转换器 - ADC IC 1 MSPS,12-Bit ADCs

GENERAL DESCRIPTION AD7495ARZ

The AD7475/AD74951 are 12-bit, high speed, low power,

successive-approximation ADCs that operate from a single

2.7 V to 5.25 V power supply with throughput rates up to 1 MSPS.

They contain a low noise, wide bandwidth track-and-hold

amplifier that can handle input frequencies above 1 MHz.

The AD7475/AD7495 use advanced design techniques to

achieve very low power dissipation at high throughput rates.

With 3 V supplies and a 1 MSPS throughput rate, the AD7475

consumes just 1.5 mA, while the AD7495 consumes 2 mA. With

5 V supplies and 1 MSPS, the current consumption is 2.1 mA

for the AD7475 and 2.6 mA for the AD7495.
