Key Features
- Dual 8-bit DAC channels with independent SPI-programmable output levels from 0 V to 4.176 V using internal 2.048 V reference
- Hardware LDAC pin enables simultaneous update of both DAC outputs, critical for applications requiring synchronized analog signals
- 2.7 V to 5.5 V supply range in a through-hole 8-pin PDIP package, ideal for prototyping and hand-soldering in lab environments
Applications
MCP4802-E/P is used in microcontroller-based systems that need two independent analog output voltages generated via SPI, such as waveform generators, motor speed references, and sensor simulation benches. The dual-channel design with simultaneous LDAC update allows phase-coherent audio or control signal generation without output glitching. Its 8-pin PDIP form factor simplifies breadboard prototyping and direct insertion into development boards.

Frequently Asked Questions
Can MCP4802-E/P update both DAC channels simultaneously, and why does simultaneous update matter in control applications?
Yes, MCP4802-E/P provides a hardware LDAC pin that, when toggled low, simultaneously transfers the programmed values from both input registers to the DAC outputs within the same clock cycle. In motor control or audio applications this eliminates the phase skew that occurs when channels are updated sequentially, ensuring both analog outputs change at exactly the same time.
What is the output voltage range of MCP4802-E/P, and does it require an external reference?
MCP4802-E/P includes an internal 2.048 V band-gap reference with a selectable 1x or 2x gain, providing a maximum output of 2.048 V or 4.096 V respectively. The maximum specified output is 4.176 V on a 5 V supply. No external reference IC is needed, reducing BOM count and simplifying the PCB layout for embedded analog output stages.
How does the 8-bit resolution of MCP4802-E/P compare to a 12-bit DAC, and when is 8-bit sufficient?
An 8-bit DAC provides 256 output steps over the full-scale range, giving approximately 8 mV per LSB on a 2.048 V reference output. A 12-bit DAC offers 4096 steps, or about 0.5 mV per LSB. For applications like LED dimming, coarse motor speed reference, and audio tone generation where sub-millivolt precision is not critical, the 8-bit MCP4802-E/P offers a lower-cost, simpler solution with adequate dynamic range.
