MCP48CVB24T-20E/ST

Digital To Analog Converters Overview

The MCP48CVB24T-20E/ST is a quad-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features buffered voltage outputs and volatile memory for DAC codes. 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 an 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 of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Quad-channel architecture providing four independent buffered voltage outputs within a single integrated circuit.
• SPI-compatible serial interface enabling high-speed data transfer with support for multiple clock polarity and phase modes.
• Configurable power-down modes that allow output buffers to be disconnected or connected to internal pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring precise analog signal generation
• Low-power portable instrumentation devices
• Data acquisition systems needing multi-channel analog outputs

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels, as the device supports both standard and reduced specification ranges. Confirm that the volatile memory requirement aligns with application needs, as values are lost upon power loss. Check for availability of development tools if programming nonvolatile options is required for similar variants.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel configuration is required alongside 12-bit resolution. Consider the SPI interface speed requirements, noting the distinction between write and read maximum frequencies. Evaluate the power supply constraints, particularly if operation below 2.7V is necessary, as analog specifications may be reduced. Verify that volatile memory behavior is acceptable for the intended application environment.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXBX4/8 family of digital-to-analog converters. The 'C' indicates the series, 'V' denotes volatile memory, 'B' specifies the buffer type, '2' represents 12-bit resolution, and '4' identifies the quad-channel count. The suffix '/ST' confirms the 20-lead TSSOP packaging option.
