1. MCP4725 Digital-to-Analog Converter
Presented by: Alex Pugh, Andrew Page, Nick Gabrisko

2. Features of this chip 12-bit resolution On-board non-volatile memory
Low power consumption (power-down mode)
I2C

3. How does it work? It converts a series of impulses into an approximate
Analog signal. VDD acts as a reference voltage, and
It takes in digital inputs and
Converts them to analog relative
To that.

4. Quantization Error
Since it approximates analog signals with impulses, it doesn’t exactly reproduce the analog signal. It is seen in the form of low-level noise in a signal, which in most applications isn’t significant.

5. Examples of usage Speaker Set-point or Offset Trimming
Sensor Calibration
Motor Speed Control
