LTC2634CMSE-LMI10#TRPBF

Overview

The LTC2634CMSE-LMI10#TRPBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference providing a 2.5V full-scale output and operates from a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the temperature range, and communicates via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Quad 10-bit resolution with integrated 2.5V precision reference
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV·s)
• SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the LMI10 configuration matches the required 10-bit resolution and mid-scale power-on reset behavior for internal reference applications.

Selection Notes

Select this part when a quad DAC configuration with 10-bit resolution and a fixed 2.5V full-scale output is required. The internal reference eliminates the need for external components, simplifying board space. Choose the MSOP package if leaded surface-mount compatibility is preferred over QFN. Verify that the 2.7V to 5.5V supply range meets system power constraints.

Part Context

This component belongs to the LTC2634 family of quad DACs, which also offers 8-bit and 12-bit resolutions. Variants exist with different full-scale voltages (2.5V or 4.096V), power-on reset behaviors (zero-scale or mid-scale), and package types (QFN or MSOP). The CMSE-LMI10 specifically denotes the commercial temperature grade, MSOP package, mid-scale internal reset, and 10-bit resolution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-model comparisons within the same family require verification of pinout compatibility and electrical parameter alignment.
