FEATURES
DESCRIPTION
The ADS8319 is a 16-bit, 500-KSPS analog-to-digital
500-kHz Sample Rate
converter. It operates with a 2.25-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, Single-Ended Input, Range: 0 V to
The device includes a 50-MHz SPI compatible serial
V
ref
interface. The interface is designed to support daisy
chaining or cascading of multiple devices. Also a
SPI Compatible Serial Interface with Daisy
Busy Indicator makes it easy to synchronize with the
Chain Option
digital host.
Excellent Performance:
The ADS8319 unipolar single-ended input range
93.6 dB SNR Typ at 10-kHz I/P
supports an input swing of 0 V to +V
ref
.
–106 dB THD Typ at 10-kHz I/P
Device operation is optimized for very low power
±1.5 LSB Max INL
operation, and the power consumption directly scales
±1.0 LSB Max DNL
with speed. This feature makes it attractive for lower
Low Power Dissipation: 18 mW Typ at 500
speed applications.
