MCP4902T-E/SL

Digital To Analog Converters Overview

The MCP4902T-E/SL is a dual-channel, 8-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features an SPI-compatible serial interface supporting clock frequencies up to 20 MHz and operates on a single supply voltage ranging from 2.7V to 5.5V. The device provides rail-to-rail buffered voltage outputs with selectable unity or 2x gain settings. It includes double-buffered input registers for simultaneous DAC updates via the LDAC pin and incorporates hardware shutdown capabilities. The component is specified for operation across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with independent output amplifiers
• SPI compatible serial interface with high-speed clock support
• Configurable output gain selection for flexible voltage scaling
• Simultaneous update capability using latch synchronization

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Cross-reference the manufacturer part number with the datasheet revision history to confirm compatibility with current design requirements.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with external voltage reference inputs is required. The 8-bit resolution suits applications where moderate precision is sufficient. Consider the 2x gain option if the system requires output voltages exceeding the reference input level. Verify that the operating environment falls within the specified extended temperature range limits.

Digital To Analog Converters Part Context

This device belongs to the MCP49X2 family of dual voltage-output DACs, which also includes the 10-bit MCP4912 and 12-bit MCP4922 variants. All members share identical pinouts, interfaces, and functional architectures, differing primarily in resolution and linearity specifications. This family utilizes a resistive string architecture to ensure monotonicity and fast settling times.

Digital To Analog Converters Replacement Considerations

The MCP4912T-E/SL and MCP4922T-E/SL are direct pin-compatible substitutes offering higher resolution. For single-channel applications, the MCP4901T-E/SL serves as a compatible alternative. Ensure that any replacement maintains the same SOIC-14 package configuration and electrical characteristics.
