LTC2636IDE-HMX10#TRPBF

Digital To Analog Converters Overview

The LTC2636IDE-HMX10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated high-accuracy 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 utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It incorporates double-buffered data latches and hardware clear (CLR) and asynchronous DAC update (LDAC) pins. The part is housed in a 16-lead MSOP package and guarantees monotonicity over the industrial temperature range of –40°C to 85°C.

Digital To Analog Converters Feature Summary

• Octal 10-Bit Resolution: Provides eight independent 10-bit DAC channels with guaranteed monotonicity.
• Integrated Reference: Features a 10ppm/°C internal reference yielding a 4.096V full-scale output.
• Power-On Reset: Configured for mid-scale reset in external reference mode upon power-up.
• Low Power Consumption: Draws approximately 1.1mA at 5V with internal reference enabled.

Digital To Analog Converters Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix HMX10#TRPBF against official Analog Devices documentation to confirm the mid-scale reset behavior in external reference mode and tape-and-reel packaging quantity. Ensure the design supports the 4.5V to 5.5V supply requirement and 16-lead MSOP footprint.

Digital To Analog Converters Selection Notes

Select this component when eight independent voltage outputs are required with a fixed 4.096V span. The H-grade suffix indicates suitability for automotive applications up to 125°C, though this specific I-grade part is rated for –40°C to 85°C. Choose the MX suffix if mid-scale initialization in external reference mode is necessary for system safety or synchronization.

Digital To Analog Converters Part Context

This part belongs to the LTC2636 family of octal DACs, which also includes 8-bit and 12-bit variants. The 'I' designation specifies the industrial temperature grade, distinguishing it from commercial (C) and automotive/harsh environment (H) grades. The 'MS' package code identifies the 16-lead Mini Small Outline Package, offering additional control pins like CLR and LDAC compared to the DFN variant.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include LTC2636IDE-LMX10#TRPBF for a 2.5V full-scale output or LTC2636IDE-HMZ10#TRPBF for zero-scale power-on reset. Cross-family replacements such as the LTC2637 offer I2C compatibility instead of SPI.

Digital To Analog Converters FAQ

What is the full-scale output voltage for the LTC2636IDE-HMX10?

The full-scale output voltage is 4.096V when operating in internal reference mode.

How does the HMX10 suffix affect power-on behavior?

The MX suffix configures the power-on reset circuit to set all DAC outputs to mid-scale when using an external reference voltage.
