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.

RECOMMENDED OPERATING CONDITIONS

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.)
