DESCRIPTION  
The ADS8512 is a complete low-power, single 5-V  
supply, 12-bit sampling analog-to-digital (A/D)  
converter.  
It  
contains  
a
complete  
12-bit  
capacitor-based, successive approximation register  
(SAR) A/D converter with sample-and-hold (S/H),  
clock, reference, and serial data interface. The  
converter can be configured for a variety of input  
ranges including ±10 V, ±5 V, 0 V to 10 V, and 0.5 V  
to 4.5 V. A high-impedance, 0.3-V to 2.8-V input is  
also available with input impedance greater than 10  
MΩ. For most input ranges, the input voltage can  
swing to 25 V or –25 V without damage to the  
converter.

ADS7813/8513  
An SPI-compatible serial interface allows data to be  
synchronized to an internal or external clock. The  
ADS8512 is specified at 40-kHz sampling rate over  
the –40°C to +85°C industrial temperature range.
