Overview
The MCP48CMB21-E/UN is a single-channel, 12-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It provides a buffered voltage output and communicates via a four-wire SPI interface with write speeds up to 50 MHz. The device operates within an analog supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced specifications. It supports reference sources including VDD, an external VREF pin, or an internal 1.214V band gap. Key electrical parameters include a typical settling time of 16 µs, ±1 LSB Integral Nonlinearity (INL), and ±1 LSB Differential Nonlinearity (DNL). The component is housed in a 10-lead MSOP package and functions across an extended temperature range of -40°C to +125°C.
Feature Summary
- Integrates user-programmable MTP memory allowing up to 32 write cycles per location for storing configuration and output values.
- Offers flexible DAC voltage reference selection between the device supply voltage, an external pin, or an internal band gap source.
- Supports configurable output gain options of 1x or 2x when utilizing an external voltage reference.
- Includes power-down modes that disconnect the output buffer or select specific pull-down resistor values.
Applications
- Set point or offset trimming
- Sensor calibration
- Low-power portable instrumentation
- PC peripherals
- Data acquisition systems
Procurement Notes
Verify the ordering suffix against the manufacturer's official documentation to confirm the specific package type and temperature grade. Ensure the procurement channel provides valid traceability for the Microchip Technology part number. Confirm compliance requirements such as RoHS status prior to finalizing orders.
Selection Notes
Select this model when a single-channel 12-bit resolution is required alongside persistent data storage capabilities. Consider the MTP memory endurance limit of 32 cycles during design planning. Verify that the application environment remains within the specified operating voltage and temperature ranges to maintain full performance specifications.
Part Context
This component belongs to the MCP48CXBXX family of digital-to-analog converters manufactured by Microchip Technology. The family encompasses both volatile and nonvolatile memory variants in single and dual-channel configurations. The MCP48CMB21 specifically denotes the single-channel, 12-bit version equipped with MTP memory technology.
Replacement Considerations
The MCP48CVB21 serves as a functional substitute if nonvolatile memory retention is not required. Other compatible alternatives within the same series include the MCP48CMB11 for 10-bit resolution or the MCP48CMB01 for 8-bit resolution, provided the channel count and package compatibility are verified.
