1 / 20 page DESCRIPTION The ADS8321 is a 16-bit sampling analog-to-digital con- verter (ADC) with tested specifications over a 4.75V to 5.25V supply range. It requires very little power even when operating at the full 100kHz data rate. At lower data rates, the high speed of the device enables it to spend most of its time in the power-down mode—the average power dissipa- tion is less than 1mW at 10kHz data rate. The ADS8321 also features a synchronous serial (SPI/SSI compatible) interface, and a differential input. The refer- ence voltage can be set to any level within the range of 500mV to VCC/2. Ultra-low power and small size make the ADS8321 ideal for portable and battery-operated systems. It is also a perfect fit for remote data acquisition modules, simulta- neous multi-channel systems, and isolated data acquisi- tion. The ADS8321 is available in an MSOP-8 package. 16-Bit, High Speed, MicroPower Sampling ANALOG-TO-DIGITAL CONVERTER FEATURES q BIPOLAR INPUT RANGE q 100kHz SAMPLING RATE q MICRO POWER: 4.5mW at 100kHz 1mW at 10kHz q POWER DOWN: 3 µA max q MSOP-8 PACKAGE q PIN-COMPATIBLE TO ADS7816 AND ADS7822 q SERIAL (SPI/SSI) INTERFACE APPLICATIONS q BATTERY OPERATED SYSTEMS q REMOTE DATA ACQUISITION q ISOLATED DATA ACQUISITION q SIMULTANEOUS SAMPLING, MULTI-CHANNEL SYSTEMS q INDUSTRIAL CONTROLS q ROBOTICS q VIBRATION ANALYSIS SAR Serial Interface Comparator ADS8321 S/H Amp DCLOCK D OUT CS/SHDN +In V REF –In CDAC ADS8321 SBAS123B – SEPTEMBER 1999 – REVISED SEPTEMBER 2004 www.ti.com PRODUCTION DATA information is current as of publication date.
