We have single channels like the \u003ca href=\"https:\/\/www.pakronics.com.au\/products\/ADA935\"\u003eMCP4725\u003c\/a\u003e and even quad channel like \u003ca href=\"https:\/\/www.adafruit.com\/product\/4470\"\u003eMCP4728\u003c\/a\u003e, but one thing most DACs have in common is they max out at whatever the input power is for the chip, which is usually 3V or 5V. The \u003cstrong\u003eAdafruit GP8403 Breakout Board \u003c\/strong\u003eis a funky exception - it has the ability to output 0-10V analog voltages, so it's useful for devices that have wide voltage input ranges - like audio or op-amps. Note that the DAC outputs have 10uF caps on them (as indicated by the datasheet), so they aren't going to be terribly fast - best for bias setting maybe, instead of trying to generate fast sine waves!\u003c\/p\u003e\n\u003cp\u003eThe GP8402 chip has a built-in I2C-to-analog signal converter that linearly converts 12-bit digital values from 0x000 to 0xFFF into two independent analog voltage outputs of 0–5V or 0–10V, with an output voltage error of 0.2%. This chip is great for when you need wide \/ high voltage range outputs thanks to its built-in booster, we also provide the 12V output from the small on-board DC\/DC converter, you can grab up to 100mA if you need to power something externally.\u003c\/p\u003e\n\u003cp\u003eOn the back are three A0, A1, and A2 address selection jumpers, so you can connect up to 8 of these DACs on one I2C bus, for up to 16 DAC outputs. Also included is a 6-pin header, for use in a breadboard. Works with both 3.3V or 5V logic, that is handled separately than the boosted DAC outputs.\u003c\/p\u003e\n\u003cp\u003eThis chip does have a non-volatile-memory capability so it will boot up into a prior-set voltage. However, it uses a funky bit-banging technique on the I2C lines so while we did get it to work on an ATmega328, you should definitely verify it on your platform since some devices will not let you 'take over' the I2C pins for bit-banging!\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/?q=gp8403\u0026amp;type=all\u0026amp;language=\u0026amp;sort=\"\u003eWe have easy-to-use Arduino and Python\/CircuitPython libraries and examples\u003c\/a\u003e that can be used with just about any microcontroller or microcomputer with I2C host - from the classic Arduino UNO-compatible to Raspberry Pi, Pico, ESP32 and beyond.\u003c\/p\u003e\n\u003cp\u003eComes with a bit of 0.1\" standard header in case you want to use it with a breadboard or perfboard.  Four mounting holes for easy attachment.
