COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or an other conditions above those
listed in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, all typical values are for 25°C ambient temperature and 5V at pin Vcc. Maximum and minimum
specifications are over the recommended operating conditions. All voltages are referred to the voltage at pin Vss. All bits in
control registers are “0”. SPI interface in “standby” (see notes 1 and 2 on page 6). Output pins unloaded. Input pins floating.
DAC input is 000hex.)
