General fttxxtrfpdfon
The Maxim MX7538 is a high performance monolithic
14-bit multiplying digitaI-to-analog converter (DAG).
The MX7538 operates with a 14-bit data bus using
standarg ghip select and memo write I ic. A Load
DAC (LDAC) signal is provided w ere doub e buffering
Wired, such as in systems with multiple DACs. If the
LDA signal is kept low, the DAC register becomes
transparentThetMX7538 ls optimized for unipolar plica-
tions, but can be operated as a bipolar DA with
additional external components.
Full accuracg is maintained over the operating temper-
ature ranget rough the use of water-level laser-trimmed.
thin-tilm resistors and temperature compensated NMOS
switches. In addition, all di ital in uts are compatible
with both TTL, 74HC and 5 CMO logic levels.
TheMX7538 is available in the narrow (0.3") 24-lead DIP
and Wide so (0.3") packages.
