It operates with a 2.048-V to 5.5-V external • 16-Bit Resolution reference. The device includes a capacitor based, • Zero Latency at Full Speed SAR A/D converter with inherent sample and hold. • Unipolar, Differential Input, Range: –Vref to Vref The devices includes a 50-MHz SPI compatible serial • SPI Compatible Serial Interface with Daisy interface. The interface is designed to support daisy chaining or cascading of multiple devices. Also a Chain Option Busy Indicator makes it easy to synchronize with the • Excellent Performance: digital host. – 95.2dB SNR Typ at 10-kHz I/P The ADS8318 unipolar differential input range – –108dB THD Typ at 10-kHz I/P supports a differential input swing of –Vref to +Vref with – ±1.0 LSB Max INL a common-mode of +Vref/2. – ±0.75 LSB Max DNL Device operation is optimized for very low power • Low Power Dissipation: 18 mW Typ at 500 operation, and the power consumption directly scales KSPS with speed. This feature makes it attractive for lower speed applications. • Power Scales Linearly with Speed: 3.6 mW/100 KSPS It is available in 10-pin MSOP and SON packages. • Power Dissipation During Power-Down State: 0.25 μW Typ • 10-Pin MSOP and SON Packages APPLICATIONS • Battery Powered Equipments • Data Acquisition Systems • Instrumentation and Process Control • Medical Electronics • Optical Networking 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.
