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 TTL/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.
The MX7226 has separate input registers for each of its
four DACs. Data is transferred into an input register from
a common 8-bit TTL/CMOS-compatible input port.
Address inputs A0 and A1 determine which DAC is
loaded when WR goes low. All DACs share a common
reference input.
For '7225 and '7226 designs utilizing a 5V supply, see the
MAX505 and MAX506 data sheet.
