A breadboard-friendly breakout board for the Analog Devices AD5330 8-bit parallel digital-to-analogue converter (DAC). All necessary pins are broken out to 2.54 mm (0.1″) spaced headers. The board includes a decoupling capacitor but no voltage regulation — supply voltage must be within the specified 2.5–5.5 V range.
Key Features
- AD5330 8-Bit DAC – Parallel interface digital-to-analogue converter from Analog Devices
- 2.5–5.5 V Supply – Low power consumption of just 115 µA at 3 V
- Configurable Output Range – GAIN pin selects 0 V to VCC or 0 V to 2×VCC
- Double-Buffered Input – LDAC pin enables simultaneous update of multiple DACs
- Power-On Reset – Output starts at 0 V until valid data is written
- Asynchronous Clear – CLR input resets all registers to zero
- Breadboard-Friendly – All pins on 2.54 mm headers with on-board decoupling capacitor
Pin Functions
- DB0–DB7 – Parallel data inputs for setting the output voltage
- CS – Chip select
- WR – Data loaded on rising edge
- GAIN – Output range selection
- LDAC – Simultaneous DAC update trigger
- CLR – Asynchronous register clear

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- CS
- CS stands for chip select, a control pin used by SPI devices to tell which connected device should listen. It matters when you connect more than one SPI module to the same microcontroller, because each device usually needs its own CS pin.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- parallel interface
- A parallel interface sends several bits of data at the same time using multiple wires. It can be faster than simple serial connections, but it uses more microcontroller pins, so it is less convenient for small projects with limited wiring space.
