_______________General Desc ription
The MX7534 and 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 2 bytes from an
8-bit bus, whereas the MX7535 operates with a 14-bit data
bus with separate MS- 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. All
devices are protected against CMOS "latchup" and do not
require 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.
