LTC2635HMSE-HMI12#TRPBF

Overview

The LTC2635HMSE-HMI12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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 low noise of 0.75mVP-P. Communication occurs via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset options include zero-scale, mid-scale, or high-impedance states.

Feature Summary

• Quad 12-bit resolution with ±2.5 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 mid-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 automotive temperature range. Confirm the MSE suffix indicates the 10-lead MSOP package. Ensure the TRPBF suffix corresponds to the tape and reel packaging format for automated assembly.

Selection Notes

Select this part when a 4.096V full-scale output is required with an internal reference. The H-grade variant necessitates a supply voltage between 4.5V and 5.5V. For lower voltage applications requiring a 2.5V full-scale output, the L-grade version is appropriate. The MSE package offers a compact 10-lead solution compared to the 16-pin QFN.

Part Context

This component belongs to the LTC2635 family of quad DACs. The HMSE-HMI12 designation specifies the H-grade (automotive), MSE package (10-lead MSOP), mid-scale power-on reset, and 12-bit resolution. Other variants exist with different resolutions (8-bit, 10-bit), reset behaviors, and package types.

Replacement Considerations

Direct replacements within the same family include other LTC2635 variants with adjusted resolution or reset configurations. Cross-package equivalents are available in the 16-pin QFN format.
