Overview
The MCP48CMB24-20E/ST is a quad-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features buffered voltage outputs and integrates Multi-Time Programmable (MTP) nonvolatile memory for power-up value retention. The device operates on a supply voltage range of 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. It utilizes a 4-wire SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. The component is housed in a 20-lead TSSOP package and supports an extended operating temperature range from -40°C to +125°C.
Feature Summary
- Integrates MTP nonvolatile memory allowing user programming up to 32 times per location for persistent configuration storage.
- Offers flexible reference voltage sourcing options including device VDD, external VREF pin, or internal band gap.
- Provides selectable output gain configurations of 1x or 2x to accommodate various signal scaling requirements.
- Includes comprehensive power management features such as Power-on/Brown-out Reset protection and configurable power-down modes.
Applications
- Set point or offset trimming in industrial control systems
- Sensor calibration circuits requiring precise analog adjustments
- Low-power portable instrumentation devices
- Data acquisition systems needing multi-channel analog output
- Motor control applications utilizing buffered voltage references
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels, particularly regarding the 1.8V to 2.7V reduced specification range if applicable. Confirm that the required SPI mode aligns with the controller's capabilities before finalizing procurement decisions.
Selection Notes
Select this component when a quad-channel DAC with nonvolatile memory retention is required. The 12-bit resolution provides 4096 steps for precise analog control. Consider the buffered output capability for driving loads directly without additional amplification. Evaluate the SPI interface speed requirements against the 50 MHz write limit to ensure system timing compliance.
Part Context
This part belongs to the MCP48CXBX4/8 family of digital-to-analog converters. The 'C' indicates the series, 'M' denotes MTP nonvolatile memory, 'B' signifies buffered voltage outputs, and '24' specifies 12-bit resolution with four channels. The '-20E/ST' suffix identifies the 20-lead TSSOP package and extended temperature rating.
Replacement Considerations
Direct substitutes within the same family include MCP48CMB24-E/ML (QFN package) or MCP48CVB24 variants (volatile memory). Verify pinout compatibility and memory type requirements when considering alternatives from other manufacturers.
