ADS7813  
SBAS043C – MARCH 1997 – REVISED SEPTEMBER 2005  
Low-Power, Serial 16-Bit Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
20µs max CONVERSION TIME  
SINGLE +5V SUPPLY OPERATION  
PIN-COMPATIBLE WITH 12-BIT ADS7812  
EASY-TO-USE SERIAL INTERFACE  
0.3" DIP-16 AND SO-16  
The ADS7813 is a low-power, single +5V supply, 16-bit  
sampling analog-to-digital (A/D) converter. It contains a  
complete 16-bit capacitor-based SAR A/D with a  
sample/hold, clock, reference, and serial data interface.  
The converter can be configured for a variety of input ranges  
including ±10V, ±5V, 0V to 10V, and 0.5V to 4.5V. A high  
impedance 0.3V to 2.8V input range is also available (input  
impedance > 10M). For most input ranges, the input  
voltage can swing to +16.5V or –16.5V without damage to  
the converter.  
±2.0LSB max INL  
87dB min SINAD  
USES INTERNAL OR EXTERNAL  
REFERENCE  
A flexible SPI-compatible serial interface allows data to be  
synchronized to an internal or external clock. The ADS7813  
is specified at a 40kHz sampling rate over the –40°C to  
+85°C temperature range. It is available in a 0.3" DIP-16 or  
an SO-16 package.
