16-Bit, High-Speed, 2.7V to 5.5V microPower Sampling  
ANALOG-TO-DIGITAL CONVERTER

FEATURES  
DESCRIPTION  
23  
16 Bits No Missing Codes (Full-Supply Range,  
High or Low Grade)  
The ADS8317 is a 16-bit, sampling, analog-to-digital  
(A/D) converter specified for a supply voltage range  
from 2.7V to 5.5V. It requires very little power, even  
when operating at the full 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. For  
example, the average power dissipation is less than  
0.2mW at a 10kHz data rate.  
Very Low Noise: 5LSBPP  
Excellent Linearity:  
±0.8LSB typ, ±1.5LSB max INL  
+0.7LSB typ, +1.25LSB max DNL  
±1mV max Offset  
±16LSB typ Gain Error  
The ADS8317 offers excellent linearity and very low  
noise and distortion. It also features a synchronous  
serial (SPI/SSI-compatible) interface and a differential  
input. The reference voltage can be set to any level  
within the range of 0.1V to VDD/2.  
microPower:  
10mW at 5V, 250kHz  
4mW at 2.7V, 200kHz  
2mW at 2.7V, 100kHz  
0.2mW at 2.7V, 10kHz  
Low power and small size make the ADS8317 ideal  
for portable and battery-operated systems. It is also  
an excellent fit for remote data-acquisition modules,  
simultaneous multichannel systems, and isolated  
data acquisition. The ADS8317 is available in  
MSOP-8 and SON-8 packages. The SON package  
size is the same as a 3x3 QFN package.
