DA Converters (DAC)
DAC (Digital-to-Analog Converter) converts digital signals into analog outputs.
- Resolution: 8-bit, 10-bit, 12-bit, 16-bit (higher = finer output)
- Reference Voltage (Vref): Sets full-scale output range
- Output Types: Voltage or current output
- Interface: SPI, I²C, Parallel
- Settling Time: Time to stabilize after input change
- Applications: Audio, motor control, signal generation
Common DAC ICs: MCP4921 (SPI, 12-bit), DAC8562 (16-bit, dual-channel)
