LTC2635HMSE-HZ12#PBF

Overview

The LTC2635HMSE-HZ12#PBF is a quad 12-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 –40°C to 125°C, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Maximum integral nonlinearity error is ±2.5 LSB.

Feature Summary

• Quad 12-bit resolution with integrated 4.096V precision reference
• Rail-to-rail output buffers with ultralow crosstalk (3nV•s)
• I²C interface with selectable power-on reset options
• Automotive temperature grade (-40°C to 125°C)

Applications

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

Procurement Notes

Verify the H suffix indicates the automotive temperature range and 4.096V internal reference. Confirm the MSE suffix corresponds to the 10-lead MSOP package. Ensure the Z suffix matches the required zero-scale power-on reset behavior. Check for lead-free compliance indicated by the PBF suffix.

Selection Notes

Select this part for applications requiring four independent 12-bit outputs with high accuracy. The 4.096V full-scale range suits 5V systems. Use the external reference mode if a different full-scale voltage is needed. Consider the QFN package if lower thermal resistance or smaller footprint is required.

Part Context

This component belongs to the LTC2635 family, which includes 8-, 10-, and 12-bit variants. The 'H' variant specifically provides a 4.096V full-scale output and requires a minimum 4.5V supply, distinguishing it from the 'L' variant which offers 2.5V full-scale and operates down to 2.7V.
