MCP48CMD22-E/MG

Digital To Analog Converters Overview

The MCP48CMD22-E/MG is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features Multi-Time Programmable (MTP) memory for nonvolatile storage of configuration and data. The device operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. It utilizes a 4-wire SPI-compatible serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. Key electrical parameters include a typical settling time of 4 µs, an internal bandgap reference of 1.214V, and an operating temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated MTP memory allows user programming of DAC values and configuration registers without external EEPROM.
• Supports multiple voltage reference sources including VDD, external VREF pin, and internal bandgap.
• Features hardware latch (LAT) pin for simultaneous updating of both DAC outputs.
• Includes power-down modes that disconnect the output buffer or engage pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration and signal conditioning
• Low-power portable instrumentation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the LAT/HVC pin circuitry supports the required high-voltage level for MTP programming if persistent storage is utilized. Confirm compatibility with the system's SPI clock speed and voltage levels before integration.

Digital To Analog Converters Selection Notes

Select this component when nonvolatile storage of DAC settings is required to maintain state after power loss. The dual-channel architecture simplifies board design for applications needing two synchronized analog outputs. Consider the 12-bit resolution and low INL specification for precision applications. Evaluate the power consumption requirements against the active and power-down current specifications provided in the datasheet.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX1/2 family, which includes single and dual channel variants with 8, 10, and 12-bit resolutions. The 'CMD' designation indicates the presence of MTP memory, distinguishing it from volatile 'CVD' variants. The 'MG' suffix typically denotes a specific package configuration within the Microchip portfolio, such as the MSOP-10 or DFN-10 packages listed for dual-channel devices.

Digital To Analog Converters Replacement Considerations

For volatile memory requirements, consider the MCP48CVD22 series. For single-channel applications, the MCP48CMD21 series is available. Lower resolution options like the MCP48CMD12 or MCP48CMD02 may be suitable if 12-bit precision is not required. Verify pinout compatibility when substituting with other packages in the same family.
