General Description
Maxim's MX7225 and MX7226 each contain four 8-bit volt-
age-output digital-to-analog converters (DACs). They
include output buffer amplifiers and input logic for simple
microprocessor and ITL/CMOS interfaces. 8-bit perfor-
mance is achieved over the full operating temperature
range without external trimming.
The MX7225 contains double-buffered logic inputs that
allow all analog outputs to be simultaneously updated
using one control signal. There are also four separate ref-
erence inputs so that the range of each DAC can be
independently set.
