DIGITAL CHARACTERISTICS (T

A = 25° C; VL = 1.7 V - 3.6 V; GND = 0 V)

ABSOLUTE MAXIMUM RATINGS (GND = 0V; all voltages with respect to ground.)

WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is

not guaranteed at these extremes.

RECOMMENDED OPERATING CONDITIONS (GND = 0V; all voltages with respect to ground.)

Notes: 10. To prevent clipping the outputs, VA_HPMIN is limited by the Full-Scale Output Voltage VFS_HP, where

VA_HP must be 200 mV greater than VFS_HP. However, if distortion is not a concern, VA_HP may be

as low as 0.9 V at any time.
