LTC2634IMSE-HZ12#TRPBF

Overview

The LTC2634IMSE-HZ12#TRPBF is a quad 12-bit voltage output DAC in a 10-lead MSOP package. It features an integrated precision reference with 10ppm/°C drift, providing a 4.096V full-scale output. The device operates from a 4.5V to 5.5V supply and includes rail-to-rail output buffers. Key specifications include ±2.5 LSB maximum INL, guaranteed monotonicity over -40°C to 125°C, and a 50MHz SPI-compatible interface. The part is AEC-Q100 qualified for automotive applications and powers on to zero-scale.

Feature Summary

• Quad 12-bit resolution with ±2.5 LSB max INL
• Integrated 4.096V reference (10ppm/°C)
• AEC-Q100 Grade H qualification (-40°C to 125°C)
• Power-on reset to zero-scale

Applications

• Automotive systems
• Process control
• Industrial automation

Procurement Notes

Verify the #TRPBF suffix indicates a tape and reel quantity of 2,500 pieces. Confirm the MSE package corresponds to the 10-lead MSOP form factor. Ensure the H grade matches the required -40°C to 125°C operating temperature range for the specific application environment.

Selection Notes

Select this model when a 4.096V internal reference is required with zero-scale power-up behavior. The 10-lead MSOP package is suitable for space-constrained designs compared to the 16-lead QFN variant. Verify that the system supply voltage remains within the 4.5V to 5.5V range specified for the H-grade devices.

Part Context

This component belongs to the LTC2634 family of quad DACs. Variants differ by resolution (8/10/12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset state (zero or mid-scale). The IMSE designation specifies the Industrial/Automotive temperature grade and MSOP package type.

Replacement Considerations

Direct substitutes include other LTC2634 variants with different resolutions or reset states, provided the electrical parameters meet requirements. Cross-family replacements require verification of pin compatibility and reference architecture.
