AD7228A
FUNCTIONAL BLOCK DIAGRAM GENERAL DESCRIPTION The AD7228A contains eight 8-bit voltage-mode digital-toanalog converters, with output buffer amplifiers and interface
logic on a single monolithic chip. No external trims are required
to achieve full specified performance for the part.
Separate on-chip latches are provided for each of the eight D/A
converters. Data is transferred into the data latches through a
common 8-bit TTL/CMOS (5 V) compatible input port. Address inputs A0, A1 and A2 determine which latch is loaded
when WR goes low. The control logic is speed compatible with
most 8-bit microprocessors.
Specified performance is guaranteed for input reference voltages
from +2 to +10 V when using dual supplies. The part is also
specified for single supply +15 V operation using a reference of
+10 V and single supply +5 V operation using a reference of …
