Low Power CMOS: 420 mW Typ
fier and a 12-bit A/D converter. The CDS and input clamp may
be disabled for CIS applications.
The internal registers are programmed using a 3-wire serial
interface and provide adjustment of the gain, offset and operat-
ing mode.
The AD9816 operates from a +5 V supply, typically consumes
420 mW of power and is packaged in a 44-lead MQFP.
