LTC2635CMSE-HZ12#TRPBF

Overview

The LTC2635CMSE-HZ12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers and guarantees monotonicity over the –40°C to 125°C automotive temperature range. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include a maximum integral nonlinearity error of ±2.5 LSB and low noise performance.

Feature Summary

• Quad 12-bit resolution with integrated 4.096V precision reference
• Automotive temperature grade (-40°C to 125°C)
• Rail-to-rail output buffers with guaranteed monotonicity
• I²C interface with selectable power-on reset states

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the H-grade specification aligns with the required 4.5V to 5.5V operating voltage range for the application.

Selection Notes

Select this part when four independent 12-bit channels are required in a compact surface-mount package. The H-grade variant is necessary for applications requiring a 4.096V full-scale output and operation within the extended automotive temperature range. Verify that the system supply voltage remains between 4.5V and 5.5V to meet electrical specifications.

Part Context

This component belongs to the LTC2635 family of quad DACs, which also offers 10-bit and 8-bit resolutions. Variants exist with different full-scale outputs (2.5V or 4.096V) and temperature grades (Commercial or Automotive). The CMSE-HZ12 specifically denotes the Commercial temperature grade version of the H-grade device in the MSOP package.

Replacement Considerations

Direct substitutes within the same package and pinout include other LTC2635 variants such as LTC2635HMI12 or LTC2635HZ12, provided the power-on reset behavior matches the design requirements. Cross-compatibility with lower-resolution versions like LTC2635HMI10 requires verification of register compatibility.
