描述

The MAX507/MAX508 are complete 12-bit, voltage-output digital-to-analog converters (DACs). The DAC output voltage and the reference have the same polarity, allowing single-supply operation. Both DACs include an internal buried-zener reference. Integrating a DAC, voltage-output amplifier, and reference on one monolithic device greatly enhances reliability over multi-chip circuits. Double-buffered logic inputs interface easily to microprocessors (µPs). Data is transferred into the input register either from a 12-bit-wide data bus (MAX507) for 16-bit µPs, or in a right-justified (8+4)-bit format (MAX508) for 8- or 16-bit µPs. All logic signals are level triggered and are TTL and CMOS compatible. Interface timing specifications insure compatibility with all common µPs.

The DACs are specified and tested for both dual-and single-supply operation. Usable supplies range from single +12V to dual ±15V. On-board gain-setting resistors allow three output-voltage ranges: 0V to +5V and 0V to +10V can be generated when using either single or dual supplies. With dual supplies, ±5V is also available. The output amplifier can drive a 2kΩ load to +10V.
