FEATURES  
DESCRIPTION  
500-kHz Sample Rate  
The ADS8319 is a 16-bit, 500-KSPS analog-to-digital  
converter. It operates with a 2.25-V to 5.5-V external  
reference. The device includes a capacitor based,  
SAR A/D converter with inherent sample and hold.  
16-Bit Resolution  
Zero Latency at Full Speed  
Unipolar, Single-Ended Input, Range: 0 V to  
Vref  
The device includes a 50-MHz SPI compatible serial  
interface. The interface is designed to support daisy  
chaining or cascading of multiple devices. Also a  
Busy Indicator makes it easy to synchronize with the  
digital host.  
SPI Compatible Serial Interface with Daisy  
Chain Option  
Excellent Performance:  
93.6 dB SNR Typ at 10-kHz I/P  
–106 dB THD Typ at 10-kHz I/P  
±1.5 LSB Max INL  
The ADS8319 unipolar single-ended input range  
supports an input swing of 0 V to +Vref.  
Device operation is optimized for very low power  
operation, and the power consumption directly scales  
with speed. This feature makes it attractive for lower  
speed applications.  
±1.0 LSB Max DNL  
Low Power Dissipation: 18 mW Typ at 500  
KSPS  
It is available in 10-pin MSOP and SON packages.  
Power Scales Linearly with Speed: 3.6 mW/100
