_______________General Desc ription
Maxim’s MX7575/MX7576 are high-speed (5μs/10μs),
microprocessor (μP) compatible, 8-bit analog-to-digital
converters (ADCs). The MX7575 provides an on-chip
track/hold function that allows full-scale signals up to
50kHz (386mV/μs slew rate) to be acquired and digi-
tized accurately. Both ADCs use a successive-approxi-
mation technique to achieve their fast conversions and
low power dissipation. The MX7575/MX7576 operate
with a +5V supply and a 1.23V external reference. They
accept input voltages ranging from 0V to 2V
REF
.
The MX7575/MX7576 are easily interfaced to all popu-
lar 8-bit μPs through standard
CS
and
RD
control sig-
nals. These signals control conversion start and data
access. A
BUSY
signal indicates the beginning and
end of a conversion. Since all the data outputs are
latched and three-state buffered, the MX7575/MX7576
can be directly tied to a μP data bus or system l/O port.
Maxim also makes the
MAX165
, a plug-in replacement
for the MX7575 with an internal 1.23V reference. For
applications that require a differential analog input and
an internal reference, the
MAX166
is recommended.
