SLAS462JUNE 2007  
16-BIT 250-KSPS SERIAL CMOS SAMPLING ANALOG-TO-DIGITAL CONVERTER  
1
FEATURES  
DESCRIPTION  
0-V to 8.192-V, ±5-V, and ±10-V Input Ranges  
90-dB SNR With 20-kHz Input  
The ADS8519 is  
a
complete 16-bit sampling  
analog-to-digital (A/D) converter using state-of-the-art  
CMOS structures. It contains a complete 16-bit,  
capacitor- based, successive approximation register  
(SAR) A/D converter with sample-and-hold,  
reference, clock, and a serial data interface. Data can  
be output using the internal clock or can be  
synchronized to an external data clock. The ADS8519  
also provides an output synchronization pulse for  
ease of use with standard DSP processors.  
±2.0 LSB Max INL  
±1 LSB Max DNL; 16-Bits No Missing Codes  
SPI Compatible Serial Output with  
Daisy-Chain (TAG) Feature and 3-State Bus  
5-V Analog Supply, 5.25 V ~ 1.65 V I/O Supply  
Pinout Similar to ADS7809 (Low Speed) and  
12-Bit ADS7808/8508  
No External Precision Resistors Required  
Uses Internal or External Reference  
100-mW Typ Power Dissipation at 250 KSPS  
32-Pin 5x5 QFN and 28-Pin SSOP Packages  
Simple DSP Interface  
The ADS8519 is specified at a 250-kHz sampling rate  
over the full temperature range. Precision resistors  
provide various input ranges including ±10 V and 0 V  
to 5 V, while the innovative design allows operation  
from a single 5-V supply with power dissipation under  
100 mW.  
The ADS8519 is available in 32-pin 5x5 QFN and  
28-pin SSOP packages, both fully specified for  
operation over the industrial -40°C to 85°C  
temperature range.
