LTC2636HMS-LMX10#PBF

Digital To Analog Converters Overview

The LTC2636HMS-LMX10#PBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and communicates via an SPI/MICROWIRE-compatible 3-wire serial interface supporting clock rates up to 50MHz. It includes double-buffered data latches and a power-on reset circuit configured to set outputs to mid-scale in external reference mode upon initialization.

Digital To Analog Converters Procurement Notes

Verify the package type corresponds to the MSOP-16 variant as indicated by the 'MS' suffix in the part number. Confirm that the specific ordering suffix matches the required power-on reset behavior and reference mode configuration documented in the manufacturer's selection guide. Ensure compatibility with the specified 4.5V to 5.5V supply range for the H-grade automotive temperature version.

Digital To Analog Converters Selection Notes

Select this component when eight independent 10-bit DAC channels are required with high accuracy and low drift. The H-grade designation indicates suitability for automotive applications operating between –40°C and 125°C. Choose the LMX10 variant specifically if mid-scale output initialization in external reference mode is necessary for system safety or startup requirements.

Digital To Analog Converters Part Context

This part belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The family offers various combinations of full-scale voltages (2.5V or 4.096V) and power-on reset behaviors. The MSOP package provides additional hardware control pins for LDAC and CLR compared to the DFN package.

Digital To Analog Converters Replacement Considerations

Compatible substitutes within the same family include LTC2636HMS-LMI10#PBF (internal reference reset) and LTC2636HMS-HZ10#PBF (zero-scale reset). For different resolutions, consider LTC2636HMS-LMX12#PBF or LTC2636HMS-LMX8#PBF.
