SBAS111C – JANUARY 1998 – REVISED JULY 2004  
12-Bit, 8-Channel, Parallel Output  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
ꢀ 2.5V INTERNAL REFERENCE  
ꢀ 8 INPUT CHANNELS  
ꢀ 500kHz SAMPLING RATE  
ꢀ SINGLE 5V SUPPLY  
ꢀ ±1LSB: INL, DNL  
The ADS7852 is an 8-channel, 12-bit Analog-to-Digital  
(A/D) converter complete with sample-and-hold, internal 2.5V  
reference and a full 12-bit parallel output interface. Typical  
power dissipation is 13mW at 500kHz throughput rate. The  
ADS7852 features both a nap mode and a sleep mode, further  
reducing the power consumption to 2mW. The input range is  
from 0V to twice the reference voltage. The reference voltage  
can be overdriven by an external voltage.  
ꢀ NO MISSING CODES  
ꢀ 70dB SINAD  
The ADS7852 is ideal for multi-channel applications where  
low power and small size are critical. Medical instrumenta-  
tion, high-speed data acquisition and laboratory equipment  
are just a few of the applications that would take advantage of  
the special features offered by the ADS7852. The ADS7852  
is available in an TQFP-32 package and is fully specified and  
ensured over the –40°C to +85°C temperature range.
