FEATURES  
DESCRIPTION  
The ADS8528/48/68 contain eight low-power, 12-,  
14-, or 16-bit, successive approximation register  
(SAR)-based analog-to-digital converters (ADCs) with  
true bipolar inputs. These channels are grouped in  
four pairs, thus allowing simultaneous high-speed  
signal acquisition of up to 650kSPS.  
2
Family of 12-, 14-, 16-Bit, Pin- and  
Software-Compatible ADCs  
Maximum Data Rate Per Channel:  
ADS8528: 650kSPS (PAR) or  
480kSPS (SER)  
ADS8548: 600kSPS (PAR) or  
450kSPS (SER)  
The devices support selectable parallel or serial  
interface  
with  
daisy-chain  
capability.  
The  
programmable reference allows handling of analog  
input signals with amplitudes up to ±12V.  
ADS8568: 510kSPS (PAR) or  
400kSPS (SER)  
The ADS8528/48/68 family supports an auto-sleep  
mode for minimum power dissipation and is available  
in both QFN-64 and LQFP-64 packages. The entire  
family is specified over a temperature range of 40°C  
to +125°C.  
Excellent AC Performance:  
Signal-to-Noise Ratio:  
ADS8528: 73.9dB  
ADS8548: 85dB  
ADS8568: 91.5dB  
Total Harmonic Distortion:  
ADS8528: 89dB
