Hello there friend! SparkFun will be closed on 8/17/2018 @2pm for a company event. We will not be offering our normal Friday tour or Local Pickups during this time. We will resume normal operations on Monday 8/20/2018. Any orders placed after 2pm MT on 8/17/2018 will be processed when we resume normal operations. Have a great day!

Breakout Board for AD5330 Parallel 8-Bit DAC

This is a simple breakout board for Analog Device’s AD5330 8-bit digital-to-analog converter (DAC). The AD5330 has a parallel interface, and can operate from a 2.5 to 5.5V supply consuming just 115uA (at 3V).

The DB0-7 pins, the parallel data inputs, are used to configure the analog output voltage. CS selects the device, and data is loaded into the input registers on the rising edge of WR. The GAIN pin allows the output range to be set at either 0V to VCC or 0V to 2VCC.

Input data to the AD5330 is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin. An asynchronous CLR input resets the contents of the input register and the DAC register to all zeros. The AD5330 also incorporates a power-on reset circuit that ensures that the DAC output powers on to 0V and remains there until valid data is written to the device.

This breadboard friendly board breaks out every necessary pin of the AD5330 to 0.1" spaced headers. The board includes a decoupling capacitor, but does not do any voltage regulation; voltage supplied to the board should be within the specified range.

Breakout Board for AD5330 Parallel 8-Bit DAC Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Customer Comments

  • The GAIN pin allows the output range to be set at either 0V to VCC or 0V to 2VCC.
    Really? First off, how can you get a gain of 2VCC? That is messed up. Second, the gain pin actually sets the range 0V to VREF or 0V to 2VREF. But since you have VREF tied to VCC, they are equal. But 2VCC makes no sense!

  • Any chance of seeing a serial input DAC, like the AD5337?
