ADS7806/8506  
capacitor-based, successive approximation register  
(SAR) A/D converter with sample and hold, clock,  
reference, and data interface. The converter can be  
configured for a variety of input ranges including ±10  
V, 4 V, and 5 V. For most input ranges, the input  
voltage can swing to 25 V or –25 V without damage  
to the converter.  
Uses Internal or External 2.5-V Reference  
Low Power Dissipation  
24 mW Typ, 30 mW Max at 40 KSPS  
50-µW Max Power Down Mode  
28-Pin SO Package  
A SPI compatible serial interface allows data to be  
synchronized to an internal or external clock. A full  
parallel interface with BYTE select is also provided to  
allow the maximum system design flexibility. The  
ADS8507 is specified at 40 kHz sampling rate over  
the industrial -40°C to 85°C temperature range.
