LTC2635HUD-HZ10#TRPBF

Overview

The LTC2635HUD-HZ10#TRPBF 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 supply ranging from 4.5V to 5.5V and communicates via 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 configured to zero-scale.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• I2C-compatible interface with selectable slave addresses
• Power-on reset to zero-scale in internal reference mode

Applications

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

Procurement Notes

Verify that the H suffix confirms the automotive temperature grade (–40°C to 125°C) and the Z suffix indicates the specific power-on reset behavior for this part number. Confirm the #TRPBF suffix corresponds to the tape and reel packaging format required for automated assembly processes.

Selection Notes

Select this component when a 4.096V full-scale output is required within a 4.5V to 5.5V supply range. The H-grade variant is necessary for applications operating between –40°C and 125°C. Ensure the system utilizes an I2C bus capable of 400kHz clock rates for optimal data throughput.

Part Context

This part belongs to the LTC2635 family of quad DACs, which also includes 8-bit and 12-bit variants. The 'H' designation distinguishes it from the 'L' grade by providing a higher 4.096V full-scale output and extended automotive temperature capability, whereas the 'L' grade offers a 2.5V output and lower minimum supply voltage.
