MCP4902T-E/ST

Digital To Analog Converters Overview

The MCP4902T-E/ST is a dual-channel, 8-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It operates on a single supply voltage ranging from 2.7V to 5.5V and features an SPI-compatible serial interface with clock support up to 20 MHz. The device utilizes a resistive string architecture to achieve fast settling times of 4.5 µs and low differential non-linearity error. It includes rail-to-rail buffered voltage outputs, selectable unity or 2x gain settings, and external multiplier mode capabilities. The component supports simultaneous latching of both DAC channels via the LDAC pin and incorporates hardware shutdown functionality for power management.

Digital To Analog Converters Feature Summary

• Dual-channel 8-bit resolution with rail-to-rail buffered voltage outputs
• SPI compatible serial interface supporting high-speed clock rates
• Simultaneous output updates using the LDAC synchronization pin
• Configurable output gain selection between unity and 2x amplification

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Precision selectable voltage reference generation
• Motor control feedback loop implementation
• Digitally-controlled multiplier or divider circuits
• Calibration of optical communication devices

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure that the procurement channel provides valid traceability for the electronic component. Cross-reference the part number with the latest datasheet revision to confirm compatibility with system requirements before finalizing acquisition.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel, 8-bit resolution is required for applications needing fast settling times and low noise performance. Consider the external voltage reference input capability if precise full-scale range adjustment is necessary. Evaluate the SPI interface speed requirements against the 20 MHz maximum clock limit. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Digital To Analog Converters Part Context

This device belongs to the MCP49X2 family of dual voltage-output digital-to-analog converters. It shares architectural similarities with the MCP4912 and MCP4922 models, differing primarily in resolution. The family is designed for consumer and industrial applications requiring signal calibration or compensation. It complements other Microchip data converter products offering varying bit depths and channel configurations.

Digital To Analog Converters Replacement Considerations

The MCP4912T-E/ST and MCP4922T-E/ST are direct functional substitutes within the same package, offering higher resolutions. For single-channel requirements, the MCP4901T-E/ST may be considered. Verify pinout compatibility and software register mapping when substituting across the family.
