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-digi-  
tal converter (A/D) complete with sample-and-hold,  
internal 2.5V reference and a full 12-bit parallel output  
interface. Typical power dissipation is 13mW at 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 volt-  
age can be overdriven by an external voltage.  
GUARANTEED NO MISSING CODES  
70dB SINAD  
LOW POWER: 13mW  
TQFP-32 PACKAGE  
The ADS7852 is ideal for multi-channel applications  
where low power and small size are critical. Medical  
instrumentation, high-speed data acquisition and labo-  
ratory 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 guaran-  
teed over the –40°C to +85°C temperature range.
