Key Features
- 12-bit resolution with 0.01 V to 5.46 V output range provides 4096 quantization levels for fine-grained analog voltage control
- Non-volatile output register retains DAC codes through power cycles, enabling power-on output without host MCU initialization
- Dual-channel SPI-programmable DAC in a compact 10-pin MSOP package reduces BOM count for two-output analog generation applications
Applications
The MCP48FEB21-E/UN is used in programmable bias voltage generation, sensor excitation, and closed-loop control reference circuits where 12-bit accuracy and non-volatile power-on state are required. Its dual-channel architecture supports simultaneous control of two analog outputs such as differential signal references or independent gain and offset trim voltages in data acquisition systems. Industrial process control transmitters and portable calibration instruments benefit from the non-volatile DAC memory, ensuring repeatable startup conditions without firmware overhead.

Frequently Asked Questions
How does the non-volatile register in the MCP48FEB21-E/UN benefit embedded systems that power-cycle frequently?
The MCP48FEB21-E/UN stores the last programmed 12-bit DAC codes in non-volatile memory, so on power-up the analog outputs immediately drive the stored voltage levels without waiting for SPI communication from the host MCU. In systems with slow boot times or those requiring deterministic output voltage within microseconds of power application, this eliminates the glitch period where the DAC output would otherwise be at 0 V or an undefined state during firmware initialization.
For a dual-rail bias supply design, what output voltage range does each channel of the MCP48FEB21-E/UN provide?
Each channel of the MCP48FEB21-E/UN spans 0.01 V minimum to 5.46 V maximum analog output, giving approximately 5.45 V of programmable range across 4096 steps with a 12-bit code. The two independent channels can be set to different voltage levels simultaneously, enabling asymmetric dual-output bias generation such as +2.5 V and +4.0 V reference rails for a differential ADC input stage from a single 5 V supply.
How does the 12-bit resolution of the MCP48FEB21-E/UN compare to 8-bit DACs for precision analog trimming?
A 12-bit DAC provides 4096 output steps versus only 256 steps for an 8-bit device, representing a 16x improvement in resolution. Over a 5 V output range, each 12-bit step is approximately 1.2 mV compared to 19.5 mV per step for an 8-bit DAC. This finer granularity is essential in closed-loop calibration and gain-setting circuits where trimming accuracy below 5 mV is required to meet 0.1% system-level accuracy specifications.
