LTC2634CMSE-HZ10#TRPBF

Overview

The LTC2634CMSE-HZ10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers and is guaranteed monotonic over the operating temperature range. Communication is handled via an SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. This specific variant utilizes a 10-lead MSOP package, incorporates a power-on reset circuit that clears outputs to zero-scale, and delivers low power consumption of 0.7mA at 5V.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• SPI/MICROWIRE compatible 3-wire serial interface (up to 50MHz)
• Power-on reset to zero-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive applications

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging containing 2,500 pieces. Confirm the MSE designation corresponds to the 10-lead MSOP package type. Ensure the H grade matches the required -40°C to 125°C automotive temperature range specifications.

Selection Notes

Select this part for applications requiring four independent 10-bit channels with a fixed 4.096V full-scale range. The H-grade version supports higher operating temperatures compared to C or I grades. Choose this model if zero-scale initialization upon power-up is required for system safety or stability.

Part Context

This component belongs to the LTC2634 family, which offers 8-, 10-, and 12-bit resolutions in both QFN and MSOP packages. The CMSE-HZ10 variant specifically combines the commercial temperature grade, MSOP footprint, high-voltage reference, and zero-scale reset configuration within the broader product line.

Replacement Considerations

Other members of the LTC2634 family may serve as alternatives depending on resolution or package requirements. Variants such as LTC2634IMSE-HZ10 differ only in temperature grade. Models with different reset behaviors like MI or MX suffixes require verification of power-up state compatibility.
