Exar Corporation MP7628
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. The readback function allows the user to poll or read the data latches, eliminating the need for storing information in RAM. 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.| Part No. | MP7628 |

APPLICATIONS
Requiring Data ReadbackGENERAL DESCRIPTION
Separate on-chip latches are provided for each DAC to allow easy microprocessor interface. In the event the microprocessor power supply is interrupted, it can poll the DACs to establish the last known system state. Data 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.
