_______________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.
