LTC2635HUD-HZ10#PBF

Overview

The LTC2635HUD-HZ10#PBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. 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 supply ranging from 4.5V to 5.5V and utilizes a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and a power-on reset circuit configurable for zero-scale, mid-scale, or high-impedance states.

Feature Summary

Quad 10-bit resolution with ±1 LSB maximum INL error
Integrated 4.096V full-scale reference with 10ppm/°C drift
Automotive temperature grade (–40°C to 125°C)
I2C interface with selectable power-on reset options

Applications

Process control and industrial automation
Power supply margining
Portable equipment

Procurement Notes

Verify the H suffix confirms the automotive temperature range and 4.5V minimum supply requirement. Confirm the Z suffix indicates power-on reset to zero-scale in internal reference mode. Ensure the UD package designation matches the required 16-pin QFN footprint. Validate the PBF suffix for lead-free compliance against project specifications.

Selection Notes

Select this part when a 4.096V internal reference is required for 10-bit accuracy in automotive environments. The 4.5V to 5.5V supply constraint distinguishes it from the L-grade variant. Consider the external reference capability if a different full-scale voltage is needed. Verify I2C address configuration via CA pins if multiple devices are present.

Part Context

This component belongs to the LTC2635 family of quad DACs, which also includes 8-bit and 12-bit variants. The H-grade subfamily is specifically designed for higher voltage operation and automotive reliability compared to the commercial C-grade. The HUD package identifies the 16-pin QFN form factor used in space-constrained designs.
