Product Details
The MX7245/MX7248 are complete, 12-bit digital-to-analog converters (DACs) that include internal voltage reference and a voltage-output amplifier. The MX7245/MX7248 are pin and electrically compatible with Analog Devices' AD7245/AD7248. The MX7245/MX7248 have double-buffered logic interfaces that are easily interfaced to microprocessors (µPs). Data is transferred into the input register from a 12-bit-wide data bus (MX7245) for 16-bit µPs, or in a tight-justified (8+4)-bit format (MX7248) for 8- and 16-bit µPs. All logic signals are level triggered and are TTL and CMOS compatible. The timing specifications ensure compatibility with common µPs.
The DACs are specified and tested for both dual- and single-supply operation. Usable supplies range from single +12V to dual ±15V. Internal gain-setting resistors allow three output voltage ranges: 0V to +5V and 0V to +10V can be generated using either single or dual supplies. With dual supplies, an additional output range of ±5V is available. The output amplifier drives 2kΩ loads to +10V. See MAX507/MAX508 for detailed description.
