LTC2635HMSE-LZ10#PBF

Overview

The LTC2635HMSE-LZ10#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.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Automotive temperature grade (–40°C to 125°C)
• Power-on reset to zero-scale in internal reference mode

Applications

• Process control and industrial automation
• Portable equipment
• Automotive systems

Procurement Notes

Verify the H-grade designation confirms the 4.5V minimum supply requirement and 4.096V full-scale output. Confirm the MSE suffix indicates the 10-lead MSOP package. Ensure the LZ10 suffix specifies 10-bit resolution and zero-scale power-on reset behavior for internal reference operation.

Selection Notes

Select this part when a 4.096V output span is required with a minimum 4.5V supply. The H-grade ensures operation in automotive environments up to 125°C. Choose this model over the L-grade if the application cannot support the lower 2.7V start-up voltage or requires the higher 4.096V range.

Part Context

This component belongs to the LTC2635 family of quad DACs. The HMSE variant specifically denotes the Automotive (H) grade, MSOP (MSE) package, 10-bit resolution, and Zero-scale reset configuration. Other variants include the L-grade for lower voltage applications and different package options like QFN.
