Microprocessor-Compatible,
14-Bit DACs
_______________General Description
The MX7534/MX7535 are high-performance, CMOS,
monolithic, 14-bit digital-to-analog converters (DACs).
Wafer-level, laser-trimmed, thin-film resistors and tempera-
ture-compensated NMOS switches assure operation over
the full operating temperature range with exceptional lin-
ear and gain stability.
The MX7534 accepts right-justified data in two bytes from
an 8-bit bus, while the MX7535 operates with a 14-bit data
bus with separate MS-byte and LS-byte select controls. In
addition, all digital inputs are compatible with both TTL and
5V CMOS-logic levels. The MX7534/MX7535 are intended
for unipolar operation, but may be operated as bipolar
DACs with additional external components. Both devices
are protected against CMOS latchup, and neither requires
the use of external Schottky protection diodes.
The MX7534 is available in 20-pin narrow (0.3") DIP, wide
SO, or PLCC packages. The MX7535 is available in
28-pin, 600 mil wide DIP, wide SO, or PLCC packages.
