DEMO BOARD  
AVAILABLE  
ADS7809  
16-Bit 10µs Serial CMOS Sampling  
ANALOG-to-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
The ADS7809 is a complete 16-bit sampling analog-  
to-digital using state-of-the-art CMOS structures. It  
contains a 16-bit capacitor-based SAR A/D with S/H,  
reference, clock, and a serial data interface. Data can  
be output using the internal clock, or can be synchro-  
nized 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  
±2 LSB 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 guaranteed 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.  
USES INTERNAL OR EXTERNAL

100mW MAX POWER DISSIPATION  
20-PIN 0.3" PLASTIC DIP AND SOIC  
SIMPLE DSP INTERFACE  
The 20-pin ADS7809 is available in a plastic 0.3" DIP  
and in an SOIC, both fully specified for operation over  
the industrial –40°C to +85°C range.
