Key Features
- Dual 12-bit DAC channels provide 4096-step analog output resolution for precision voltage generation in calibration and control applications
- Non-volatile output register stores DAC codes across power cycles, enabling power-on analog output without MCU initialization
- SPI serial binary input supports high-speed host communication for real-time analog control in audio, industrial, and instrumentation designs
- 10-pin MSOP package with 0.5 mm pitch delivers a compact 3 mm × 3 mm dual-DAC solution for space-constrained PCB designs
Applications
MCP48FVB02-E/UN is used in industrial process controllers and programmable power supplies where two independent 12-bit analog output voltages must be set and retained across power cycles without MCU re-programming. Audio equipment and signal generators use it to produce precise reference or bias voltages with fine 12-bit resolution. It also suits sensor calibration rigs and medical instrumentation requiring stable, repeatable analog set-points maintained in non-volatile memory.

Frequently Asked Questions
What DAC resolution does MCP48FVB02-E/UN offer and how does 12-bit resolution translate to output step size?
MCP48FVB02-E/UN provides 12-bit resolution with 4096 discrete output codes. With a 3.3 V reference, each LSB equals approximately 0.8 mV, enabling fine analog voltage adjustments for precision calibration, sensor biasing, and motor control reference signals with minimal quantization error.
Does MCP48FVB02-E/UN retain its output values after power-off, and how does the non-volatile feature benefit production equipment?
Yes, the non-volatile output register stores the last programmed DAC code and restores it at power-up automatically, so production-calibrated equipment powers on with the correct analog trim values without any MCU initialization. This eliminates calibration firmware from the boot sequence and ensures correct output from the very first cycle, which is critical for medical devices and industrial controllers.
How does the integral non-linearity specification of MCP48FVB02-E/UN affect its use in high-accuracy voltage reference applications?
With a maximum integral non-linearity of 0.195% (approximately 8 LSB at 12 bits), MCP48FVB02-E/UN is suitable for applications requiring better than 9-bit effective linearity, such as programmable gain controls, LCD bias generators, and coarse calibration trimmers. For tighter linearity budgets below 4 LSB, a higher-grade 12-bit DAC with 0.05% INL specification may be more appropriate.
Can both DAC channels of MCP48FVB02-E/UN be updated simultaneously over SPI, and what is the communication protocol?
Both channels use a binary serial SPI interface compatible with standard 4-wire SPI at speeds up to 20 MHz, allowing sequential writes to each channel register within microseconds. A latch command updates both outputs synchronously, ensuring matched analog output transitions for dual-channel applications such as stereo audio volume or XY positioning systems that require phase-aligned output changes.
