General Description
The Maxim MX7538 is a high performance monolithic
14-bit multiplying digitaI-to-analog converter (DAC).
The MX7538 operates with a 14-bit data bus using
standard chip select and memory write logic. A Load
DAC (LDAC) signal is provided where double buffering
is reguired, such as in systems with multiple DACs. lfthe
LDAC signal is kept low, the DAC register becomes
transparent.The MX7538 is optimized for unipolar applica-
tions, but can be operated as a bipolar DAC with
additional external components.
Full accuracy is maintained over the operating temper-
ature range through the use of water-level laser-trimmed,
thin-film resistors and temperature compensated NMOS
switches. In addition, all digital inputs are compatible
with both TTL, 74HC and 5V CMOS logic levels.
TheMX7538 is available in the narrow (0.3") 24-lead DIP
and Wide so (0.3") packages.
