16-Bit 10µs Serial CMOS Sampling  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
The ADS7809 is a complete 16-bit sampling Analog-to-  
Digital (A/D) converter using state-of-the-art CMOS struc-  
tures. It contains a 16-bit capacitor-based Successive Ap-  
proximation Register (SAR) A/D converter with sample-and-  
hold, reference, clock, and a serial data interface. Data can  
be outputted using the internal clock, or can be synchronized  
to an external data clock. The ADS7809 also provides an  
output synchronization pulse for ease of use with standard  
DSP processors.  
100kHz SAMPLING RATE  
86dB SINAD WITH 20kHz INPUT  
±2LSB INL  
DNL: 16 Bits No Missing Codes  
SIX SPECIFIED INPUT RANGES  
SERIAL OUTPUT  
SINGLE +5V SUPPLY OPERATION  
PIN-COMPATIBLE WITH 12-BIT ADS7808  
The ADS7809 is specified at a 100kHz sampling rate, and  
specified over the full temperature range. Laser-trimmed  
scaling resistors provide various input ranges including ±10V  
and 0V to 5V, while an innovative design operates from a  
single +5V supply, with power dissipation under 100mW.

100mW MAX POWER DISSIPATION  
0.3" SO-20  
The ADS7809 is available in a 0.3" SO-20, and is fully  
specified for operation over the industrial –40°C to +85°C  
range.
