ICM7361/7341/7321
IC MICROSYSTEMS
SINGLE 12/10/8-BIT VOLTAGE-OUTPUT DACS
with guaranteed monotonic behavior. These DACs are
available in both a tiny 6-pin SOT-23 package and an 8-
pin MSOP package. They include a 1.25V reference for
ease of use and flexibility. The reference output is
available on a separate pin, in the 8-pin package version,
and can be used to drive external loads. The operating
supply range is 2.7V to 5.5V.
