ADS7826IDRBTG4

模数转换器 - ADC 5.25V-2.7V 10 bit 200KSPS Synch Serial

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.
