ADS7822E/2K5

12位，高速， 2.7V微功耗采样模拟数字转换器 12-Bit, High-Speed, 2.7V microPower Sampling ANALOG-TO-DIGITAL CONVERTER

DESCRIPON

The ADS7822 is a 12-bit sampling analog-to-digital A/D converter with ensured specifications over a 2.7V to 5.25V supply range. It requires very little power even when operating at the full 75kHz rate. At lower conversion rates, the high speed of the device enables it to spend most of its time in the power-down mode—the power dissipation is less than 60µW at 7.5kHz.
