LTC2634IMSE-LZ10#TRPBF

Overview

The LTC2634IMSE-LZ10#TRPBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key specifications include rail-to-rail output buffers, guaranteed monotonicity over the temperature range, and ultralow DAC-to-DAC crosstalk of 2.4nV•s. This specific variant includes a power-on reset function that clears outputs to zero-scale in internal reference mode.

Feature Summary

• Quad 10-bit resolution with integrated 2.5V precision reference
• Rail-to-rail output buffers and guaranteed monotonic operation
• 3-wire serial interface supporting clock rates 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 package type corresponds to the 10-lead MSOP configuration indicated by the IMSE suffix. Confirm the automotive grade designation if required for specific reliability standards. Ensure the tape and reel quantity matches the TR suffix specification. Cross-reference the exact part number against official distributor catalogs to confirm current availability status.

Selection Notes

Select this component when a quad DAC configuration with 10-bit resolution is required. The LZ suffix indicates a power-on reset to zero-scale, suitable for systems requiring safe initialization states. The L suffix denotes a 2.5V full-scale output, operating within a 2.7V to 5.5V supply range. Consider the MSOP package for space-constrained designs compared to the QFN option.

Part Context

This part belongs to the LTC2634 family of quad DACs available in 8-, 10-, and 12-bit resolutions. The family shares common architectural features including low noise and high accuracy references. Variations exist based on full-scale voltage (L for 2.5V, H for 4.096V), reset behavior (Z for zero-scale, MI/MX for mid-scale), and package type (UD for QFN, MSE for MSOP).

Replacement Considerations

Direct replacements within the same family include other LTC2634 variants differing only in resolution or reset behavior. For different interfaces, consider the LTC2635 I2C-compatible series. Verify pin compatibility and electrical specifications before substituting with components from other manufacturers.
