ADS7826IDRBR

10/8 /12-位高速2.7 V微功耗采样模拟数字转换器 10/8/12-BIT HIGH SPEED 2.7 V microPOWER SAMPLING ANALOG-TO-DIGITAL CONVERTER

DESCRIPON

The ADS7826/27/29 is a family of 10/8/12-bit sampling analog-to-digital converters A/D with assured specifi-cations at 2.7-V supply voltage. It requires very little power even when operating at the full sample 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 60 µW at 7.5 kHz.
