Overview
The MCP48CMB01-E/MF is a single-channel, 8-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It provides buffered voltage output with an SPI serial interface supporting up to 50 MHz write speeds. The device operates on a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. Key electrical parameters include a typical settling time of 16 µs, a gain error of ±1% FSR, and an Integral Nonlinearity (INL) specification of ±1 LSB. It supports reference sources from VDD, external VREF, or an internal band gap.
Feature Summary
- Integrates MTP nonvolatile memory allowing user-programmable storage of DAC values and configuration registers.
- Features WiperLock™ technology for simultaneous updating of volatile and nonvolatile DAC registers.
- Includes Power-on/Brown-out Reset (POR/BOR) protection and configurable power-down modes.
Applications
- Set point or offset trimming in industrial systems
- Sensor calibration circuits
- Low-power portable instrumentation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure that any custom programming requirements for the MTP memory are addressed prior to deployment. Confirm compatibility with system voltage levels and SPI timing constraints.
Selection Notes
Select this component when nonvolatile storage of the DAC output state is required without external EEPROM. Compare against the MCP48CVB01 if volatile memory is sufficient for the application. Consider the MCP48CMB02 if dual-channel output capability is needed instead of a single channel.
Part Context
This part belongs to the MCP48CXBXX family of 8/10/12-bit DACs manufactured by Microchip Technology. The 'M' indicates the MSOP-10 package, while 'MF' denotes the specific tape and reel packaging variant. The 'E' suffix specifies the extended industrial temperature range of -40°C to +125°C.
Replacement Considerations
The MCP48CVB01 serves as a direct functional substitute if nonvolatile memory retention is not required. For applications requiring dual channels, the MCP48CMB02 is the appropriate alternative within the same family.
