LTC2634HUD-HZ10#PBF

Overview

The LTC2634HUD-HZ10#PBF is a quad 10-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 a temperature coefficient of 10ppm/°C. The device operates on a single 4.5V to 5.5V supply and includes rail-to-rail output buffers that are guaranteed monotonic over the -40°C to 125°C automotive temperature range. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Upon power-up, the outputs reset to zero-scale in internal reference mode.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum Integral Nonlinearity (INL)
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• AEC-Q100 qualified for automotive applications (-40°C to 125°C)
• Power-on reset to zero-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and standard tube packaging. Confirm the H-grade designation matches the required -40°C to 125°C operating temperature range for the target application environment.

Selection Notes

Select this part when a quad DAC configuration with high accuracy and automotive reliability is required. The H-grade ensures performance at elevated temperatures, while the Z-power-on reset option prevents unintended output states during system initialization.

Part Context

This component belongs to the LTC2634 family, which offers 8-, 10-, and 12-bit resolutions in QFN and MSOP packages. The HUD variant specifically denotes the Automotive grade (H), 16-lead QFN package (UD), and Zero-scale power-on reset (Z).

Replacement Considerations

Other members of the LTC2634 family, such as the LTC2634IUD-HZ10#PBF or LTC2634CUD-HZ10#PBF, offer identical electrical specifications but differ only in their specified operating temperature ranges.
