MORE of course! So why settle for a 12-bit DAC like the \u003ca href=\"\/en-eu\/products\/adafruit-12-bit-dac-w-i2c-interface\" target=\"_blank\"\u003eMCP4725\u003c\/a\u003e when you can go for the 16-bits of the AD5693?\u003c\/p\u003e\n\u003cp\u003eOK well there may be some reason to go with 12-bits, say if you don't need high resolution output and want to go with the more affordable DAC. But for those who like the finer things in life, the \u003cstrong\u003eAdafruit AD5693R Breakout Board is a16-Bit DAC with I2C Interface\u003c\/strong\u003e and temperature compensated 2.5V internal reference  for a compact high-precision output. \u003c\/p\u003e\n\u003cp\u003eWe break out the ADDR\/A0 pin so you can connect two of these DACs on one I2C bus, just tie the A0 pin high (or close the jumper on the back) to keep it from conflicting. Also included is a 6-pin header, for use in a breadboard. Works with both 3.3V or 5V logic, and you can have the output max out at 2.5V or 5V (2xVref). If you're powering from 3.3V you will be able to set the output range to 2.5V or Vin.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAD5693R DAC Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh relative accuracy (INL): ±2 LSB maximum at 16 bits\u003c\/li\u003e\n\u003cli\u003eLow drift, 2.5 V reference: 2 ppm\/°C typical\u003c\/li\u003e\n\u003cli\u003eSelectable span output: 2.5 V or 5 V\u003c\/li\u003e\n\u003cli\u003eTotal unadjusted error (TUE): ±0.06% of FSR maximum\u003c\/li\u003e\n\u003cli\u003eOffset error: ±1.5 mV maximum\u003c\/li\u003e\n\u003cli\u003eGain error: ±0.05 % of FSR maximum\u003c\/li\u003e\n\u003cli\u003eLow glitch: 0.1 nV-sec\u003c\/li\u003e\n\u003cli\u003eHigh drive capability: 20 mA\u003c\/li\u003e\n\u003cli\u003eWide operating temperature range: −40°C to +105°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSome nice extras with this chip: for chips that have 3.4Mbps Fast Mode I2C (Arduino's don't) you can update the Vout at ~200 KHz. There's an EEPROM so if you write the output voltage, you can 'store it' so if the device is power cycled it will restore that voltage. The output voltage is rail-to-rail and proportional to the power pin so if you run it from 3.3V, the output range is 0-3.3V. If you run it from 5V the output range is 0-5V.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_AD569x\/tree\/main\"\u003eAdafruit have an easy-to-use Arduino library and tutorial with a sine-wave output example\u003c\/a\u003e that can be used with just about any microcontroller or microcomputer with I2C host.\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.
