LTC2635CUD-HMI10#PBF

Overview

The LTC2635CUD-HMI10#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 operates from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, double-buffered data latches, and ultralow crosstalk between DACs (3nV•s). Communication is handled via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset options include 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
• Rail-to-rail output buffers guaranteed monotonic over –40°C to 125°C
• Ultralow DAC-to-DAC crosstalk of 3nV•s

Applications

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

Procurement Notes

Verify the package type matches the 'UD' suffix for a 16-pin QFN. Confirm the temperature grade 'C' aligns with commercial requirements (0°C to 70°C), as the datasheet specifies automotive range for 'H' grades. Ensure the power-on reset configuration 'MI' (Mid-Scale in Internal Reference Mode) meets system startup needs.

Selection Notes

Select this part when a 4.096V internal reference is required with 10-bit accuracy. The H-grade internal reference necessitates a minimum supply voltage of 4.5V. For systems requiring lower supply voltages (2.7V–5.5V), the L-grade variant with a 2.5V full-scale output should be considered instead.

Part Context

This component belongs to the LTC2635 family of quad DACs. The specific suffixes define its attributes: 'C' indicates commercial temperature range, 'UD' denotes the 16-pin QFN package, 'H' specifies the 4.096V internal reference, 'MI' sets the power-on reset to mid-scale, and '10' defines the 10-bit resolution.
