1 / 21 page DESCRIPTION The ADS7817 is a 12-bit, 200kHz sampling Analog-to- Digital (A/D) converter that features a high impedance fully differential analog input. The reference voltage can be var- ied from 100mV to 2.5V, with a corresponding input- referred resolution between 49 µV and 1.22mV. The differential input, low power, automatic power down, and small size make the ADS7817 ideal for direct connec- tion to transducers in battery operated systems, remote data acquisition, or multi-channel applications. The ADS7817 is available in a plastic mini-DIP-8, an SO-8, or an MSOP-8 package. 12-Bit Differential Input Micro Power Sampling ANALOG-TO-DIGITAL CONVERTER FEATURES q BIPOLAR INPUT RANGE q TRUE DIFFERENTIAL INPUT q 200kHz SAMPLING RATE q MICRO POWER: 2.3mW at 200kHz q POWER DOWN: 3 µA Max q AVAILABLE IN MSOP-8 PACKAGE q SERIAL INTERFACE q AC COMMON-MODE REJECTION SAR Control Serial Interface D OUT Comparator S/H Amp CS/SHDN DCLOCK +In V REF –In CDAC OPA658 ADS7 817 ADS7817 APPLICATIONS q TRANSDUCER INTERFACE q BATTERY OPERATED SYSTEMS q REMOTE DATA ACQUISITION q ISOLATED DATA ACQUISITION q AC MOTOR CONTROL ADS7817 SBAS066A – MAY 2001 www.ti.com PRODUCTION DATA information is current as of publication date.
