1 / 28 page BurrBrown Products from Texas Instruments ADS7822 ADS7822 1 FEATURES DESCRIPTION APPLICATIONS SAR Control Serial Interface D OUT Comparator S/HAmp CS/SHDN DCLOCK +In V REF -In CDAC ADS7822 SBAS062C – JANUARY 1996 – REVISED AUGUST 2007 12-Bit, 200kHz, microPower Sampling ANALOG-TO-DIGITAL CONVERTER 2 • 200kHz Sampling Rate • microPower: The ADS7822 is a 12-bit sampling analog-to-digital (A/D) converter with ensured specifications over a 1.6mW at 200kHz 2.7V to 5.25V supply range. It requires very little 0.54mW at 75kHz power even when operating at the full 200kHz rate. At 0.06mW at 7.5kHz lower conversion rates, the high speed of the device • Power Down: 3μA max enables it to spend most of its time in the • Mini-DIP-8, SO-8, and MSOP-8 Packages power-down mode—the power dissipation is less than 60 μW at 7.5kHz. • Pseudo-Differential Input • Serial Interface The ADS7822 also features operation from 2.0V to 5V, a synchronous serial interface, and a pseudo-differential input. The reference voltage can be set to any level within the range of 50mV to VCC. • Battery-Operated Systems Ultra low power and small size make the ADS7822 • Remote Data Acquisition ideal for battery-operated systems. It is also a perfect • Isolated Data Acquisition fit for remote data-acquisition modules, simultaneous • Simultaneous Sampling, Multichannel Systems multichannel systems, and isolated data acquisition. The ADS7822 is available in a plastic mini-DIP-8, an SO-8, or an MSOP-8 package. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
