ADS7823 SBAS180B – JUNE 2001 - REVISED SEPTEMBER 2003 12-Bit, Sampling A/D Converter with I2C™ INTERFACE FEATURES www.DataSheet4U.com q 50kHz DESCRIPTION The ADS7823 is a single-supply, low-power, 12-bit data acquisition device that features a serial I2C interface. The Analog-to-Digital (A/D) converter features a sample-andhold amplifier and internal, asynchronous clock. The combination of an I2C serial two-wire interface and micropower consumption makes the ADS7823 ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The ADS7823 is available in an MSOP-8 package. q q q q q q SAMPLING RATE NO MISSING CODES 2.7V TO 5V OPERATION FOUR-WORD FILO A0, A1 ADDRESS PINS I2C INTERFACE SUPPORTS: Standard, Fast, and High-Speed Modes MSOP-8 PACKAGE APPLICATIONS q q q q q VOLTAGE SUPPLY MONITORING ISOLATED DATA ACQUISITION TRANSDUCER INTERFACE BATTERY-OPERATED SYSTEMS REMOTE DATA ACQUISITION SAR VREF SDA AIN CDAC Serial Interface Comparator SCL A0 S/H Amp A1 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.
