LTC2634CMSE-LMI10#PBF

Overview

The LTC2634CMSE-LMI10#PBF is a quad 10-bit voltage output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 85°C 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.

Feature Summary

• Quad 10-bit DACs with integrated 10ppm/°C precision reference
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
• SPI/MICROWIRE compatible 3-wire serial interface 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
• Automotive

Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance. Confirm the MSE package designation matches the required 10-lead MSOP footprint. Ensure the LMI10 code corresponds to the 10-bit resolution and mid-scale power-on reset configuration for internal reference operation.

Selection Notes

Select this part for applications requiring four independent 10-bit outputs with low drift. The 2.5V full-scale range suits single-supply systems operating between 2.7V and 5.5V. Choose this variant over H-grade parts if the system does not require 4.096V output or extended high-temperature automotive reliability.

Part Context

This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The CMSE-LMI10#PBF specifically denotes the commercial temperature grade, MSOP package, 10-bit resolution, and mid-scale internal reference reset behavior within this product line.
