MCP4725 I2C DAC Breakout board

Bought from here

#include <Wire.h>
#include <Adafruit_MCP4725.h>
Adafruit_MCP4725 dac;
#define DAV_RESOLUTION  (9)

void setup() {
  Serial.begin(9600);
  Serial.println("MCP4725 Test");

  // 0x62 default
  // 0x63 Addr pin tied to VCC
  // 0x60 Addr pin tied to GND
  dac.begin(0x60);
}

void loop() {
  for (int x=1;x<=5;x++){
    dac.setVoltage(x*4096/5, false);
    delay(50);
  }
}

Testing maximum frequency, around 800us

#include <Wire.h>
#include <Adafruit_MCP4725.h>
Adafruit_MCP4725 dac;
#define DAV_RESOLUTION  (9)

void setup() {
  Serial.begin(9600);
  Serial.println("MCP4725 Test");

  // 0x62 default
  // 0x63 Addr pin tied to VCC
  // 0x60 Addr pin tied to GND
  dac.begin(0x60);
}

void loop() {
  dac.setVoltage(1, false);
  dac.setVoltage(4095, false);
}
