ADS7830 www.ti.com SBAS302C – DECEMBER 2003 – REVISED OCTOBER 2012 8-Bit, 8-Channel Sampling ANALOG-TO-DIGITAL CONVERTER with I2C™ Interface Check for Samples: ADS7830 FEATURES 1 23 70kHz SAMPLING RATE ±0.5LSB INL/DNL 8 BITS NO MISSING CODES 4 DIFFERENTIAL/8 SINGLE-ENDED INPUTS 2.7V TO 5V OPERATION BUILT-IN 2.5V REFERENCE/BUFFER SUPPORTS ALL THREE I2C MODES: Standard, Fast, and High-Speed LOW POWER: 180μW (Standard Mode) 300μW (Fast Mode) 675μW (High-Speed Mode) DIRECT PIN COMPATIBLE WITH ADS7828 TSSOP-16 PACKAGE APPLICATIONS VOLTAGE-SUPPLY MONITORING ISOLATED DATA ACQUISITION TRANSDUCER INTERFACE BATTERY-OPERATED SYSTEMS REMOTE DATA ACQUISITION DESCRIPTION The ADS7830 is a single-supply, low-power, 8-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer. The Analogto-Digital (A/D) converter features a sample-and-hold amplifier and internal, asynchronous clock. The combination of an I2C serial, 2-wire interface and micropower consumption makes the ADS7830 ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The ADS7830 is available in a TSSOP-16 package.
