LTC2635HMSE-LMI10#PBF

Overview

The LTC2635HMSE-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 4.096V and operates from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset options include mid-scale or high-impedance states.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference (±10ppm/°C)
• Automotive temperature grade: –40°C to 125°C
• Rail-to-rail output buffers with low noise (0.75mV P-P typical)
• I²C interface with selectable power-on reset to mid-scale

Applications

• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffix LMI10#PBF against the manufacturer's current product selection guide to confirm availability and exact pinout configuration for the MSOP package. Ensure the design supports the required 4.5V to 5.5V supply voltage range for the H-grade variant.

Selection Notes

Select this part when four independent 10-bit outputs are required with an internal 4.096V reference. The H-grade designation ensures operation in automotive environments up to 125°C. Verify that the system supply voltage remains within 4.5V to 5.5V, as lower voltages may not support the full-scale output specification.

Part Context

This component belongs to the LTC2635 family, which offers 8-, 10-, and 12-bit resolutions. The HMSE suffix indicates the Automotive temperature grade (H) and the 10-lead MSOP package (MSE). The LMI10 suffix specifies the 10-bit resolution with a Mid-Scale power-on reset behavior in internal reference mode.

Replacement Considerations

Compatible substitutes within the same family include LTC2635CMSE-LMI10#PBF for commercial temperature ranges or LTC2635HMSE-HMI10#PBF if High-Impedance power-on reset is preferred instead of Mid-Scale.
