This reference design is a quad channel digital to analog converter with an integrated reference that introduces the use of DAC8004, a low-power, buffered voltage output, 16-bit, quad channel digital-to-analog converter. It incorporates a power-on-reset circuit that ensures the DAC output powers up at zero scale or mid scale depending on status of the POR pin and remains in this state until a valid code is written to the device.
The DAC80004 evaluation board of Texas Instruments provides evaluation of all aspects of the device including user control over every pin on DAC80004. It is also controlled through a serial peripheral interface that can operate at clock rates of up to 50MHz. In addition, the device allows the user to control the DAC logic using onboard jumpers, or digitally through the J2 header. By default, it is configured to be used with an onboard 2.5V external reference, but can be easily modified to use the other 5V external reference. Moreover, it can be used as a standalone board or as a daughter card to the MMB0 Modular EVM motherboard. The MMB0 motherboard can supply the digital interface as well as the power supply voltage required by the DAC80004EVM.
DACs have been used in almost all aspects of electronic devices. These are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals, which connect to the screen drivers to display monochrome or color images. This device however, is suitable for portable instrumentation, PLC analog output module, closed-loop servo control, and data acquisition systems applications.
