MX7534/MX7535 19-1116 Rev 1 11/96 Microprocessor-Compatible, 14-Bit DACs General Description Features The MX7534/MX7535 are high-performance, CMOS, 14-Bit Monotonic Over Full Temperature Range monolithic, 14-bit digital-to-analog converters (DACs). Full 4-Quadrant Multiplication Wafer-level, laser-trimmed, thin-film resistors and tempera- P-Compatible, Double-Buffered Inputs ture-compensated NMOS switches assure operation over the full operating temperature range with exceptional lin- Exceptionally Low Gain Tempco (2.5ppm/C) ear and gain stability. Low Output Leakage (<20nA) Over Temp. The MX7534 accepts right-justified data in two bytes from Low Power Consumption an 8-bit bus, while the MX7535 operates with a 14-bit data TTL and CMOS Compatible bus with separate MS-byte and LS-byte select controls. In addition, all digital inputs are compatible with both TTL and Ordering Information 5V CMOS-logic levels. The MX7534/MX7535 are intended PART TEMP. RANGE PIN-PACKAGE INL (LSBs) for unipolar operation, but may be operated as bipolar MX7534KN 0C to +70C 20 Plastic DIP 1 DACs with additional external components. Both devices MX7534JN 0C to +70C 20 Plastic DIP 2 are protected against CMOS latchup, and neither requires MX7534KCWP 0C to +70C 20 SO 1 the use of external Schottky protection diodes. MX7534JCWP 0C to +70C 20 SO 2 The MX7534 is available in 20-pin narrow (0.3 ) DIP, wide MX7534KP 0C to +70C 20 PLCC 1 SO, or PLCC packages. The MX7535 is available in MX7534JP 0C to +70C 20 PLCC 2 28-pin, 600 mil wide DIP, wide SO, or PLCC packages.
