LTC2635HUD-LMO10#TRPBF

Overview

The LTC2635HUD-LMO10#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 operates from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. The LMO suffix configures the power-on reset to place all DAC outputs in a high-impedance state.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Power-on reset to high-impedance state for safe startup
• Ultralow crosstalk between DACs (3nV•s typical)

Applications

• Process control and industrial automation systems
• Automotive electronic modules
• Portable equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's documentation to ensure correct package type, temperature grade, and power-on reset behavior. Confirm that the 16-pin QFN package requirements are met during PCB layout.

Selection Notes

Select this component when an automotive-grade quad DAC with a 4.096V internal reference is required. The LMO variant is suitable for applications necessitating a high-impedance output state upon power-up to prevent unintended signal driving.

Part Context

This part belongs to the LTC2635 family, which offers 8-, 10-, and 12-bit resolutions. The 'H' designation indicates the 4.096V full-scale version requiring a minimum 4.5V supply, while 'UD' specifies the 16-pin QFN package.

Replacement Considerations

Direct substitutes within the same family include LTC2635HUD-Z10#TRPBF (zero-scale reset) or LTC2635HUD-MI10#TRPBF (mid-scale reset). Verify compatibility if the power-on reset behavior differs from the high-impedance requirement.
