MCP4912T-E/SL

Digital To Analog Converters Overview

The MCP4912T-E/SL is a dual-channel, 10-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features buffered voltage outputs with rail-to-rail capability and operates on a single supply voltage ranging from 2.7V to 5.5V. The device utilizes an SPI-compatible serial interface supporting clock frequencies up to 20 MHz. Key electrical specifications include a typical settling time of 4.5 µs, a maximum Integral Non-Linearity (INL) error of ±3.5 LSB, and a Differential Non-Linearity (DNL) error of ±0.5 LSB. It supports selectable unity or 2x gain output configurations and includes hardware shutdown functionality.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with simultaneous latching capability via the LDAC pin for synchronized updates.
• SPI compatible serial interface allowing high-speed data transfer with support for 20 MHz clock frequencies.
• Configurable output gain selection enabling full-scale range adjustment between VREF and 2 * VREF.
• Integrated Power-on Reset (POR) circuit ensuring reliable initialization and high-impedance output states upon power-up.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the '-E' designation corresponds to the extended industrial temperature range of -40°C to +125°C. Ensure compatibility with the SOIC-14 package footprint during PCB layout verification. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Digital To Analog Converters Selection Notes

Select the MCP4912T-E/SL when a dual-channel solution with 10-bit resolution is required for cost-sensitive applications. This model is appropriate where moderate accuracy is sufficient compared to the 12-bit MCP4922 series. Consider the external reference input requirement if internal references are not utilized. Evaluate the 2.7V minimum supply voltage against system power constraints.

Digital To Analog Converters Part Context

This component belongs to the MCP49X2 family of dual DACs, which also includes the 8-bit MCP4902 and the 12-bit MCP4922. All members share identical pinouts, interfaces, and general electrical characteristics, differing primarily in resolution and linearity specifications. The T-E/SL suffix denotes the reel packaging, industrial temperature grade, and SOIC-14 package type.

Digital To Analog Converters Replacement Considerations

The MCP4912-E/ST serves as a direct functional replacement offering the same specifications in a TSSOP-14 package. For higher resolution requirements within the same family, the MCP4922T-E/SL provides 12-bit performance with identical pinouts. Single-channel alternatives like the MCP4911 series require separate components for dual-channel functionality.
