NOTES:
1 Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps (HP5082-2835) from input pin to the supplies.

The MP7628 is a quad 8-bit Digital-to-Analog Converter designed using a decoded DAC architecture featuring excellent DAC-to-DAC matching and guaranteed monotonicity.

Separate on-chip latches are provided for each DAC to allow easy microprocessor interface.

The readback function of MP7628 allows the user to poll or read the data latches, eliminating the need for storing information in RAM. In the event the microprocessor power supply is interrupted, it can poll the DACs to establish the last known system state.

Data of MP7628 is transferred into any of the four DAC data latches via common 8-bit TTL/CMOS compatible input port. Control inputs DS1, DS2 and A/B determine which DAC is to be loaded. The MP7628's load cycle is similar to the write cycle of a random access memory and the device is bus compatible with most 8-bit microprocessors.

The MP7628 operates at +5 V power supply and dissipates less than 5mW.

All DACs MP7628 offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.
