LTC2635CUD-LMI10#PBF

Overview

The LTC2635CUD-LMI10#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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It includes rail-to-rail output buffers, double-buffered data latches, and a power-on reset circuit configured to reset outputs to mid-scale in internal reference mode. Communication is handled via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.

Feature Summary

Quad 10-bit resolution with maximum INL error of ±1 LSB
Integrated 2.5V precision reference with 10ppm/°C drift
Power-on reset to mid-scale in internal reference mode
Ultralow DAC-to-DAC crosstalk of 3nV•s

Applications

Mobile communications
Process control and industrial automation
Power supply margining
Portable equipment

Procurement Notes

Verify the package type matches the 'UD' suffix for the 16-pin QFN form factor. Confirm the 'LMI10' designation ensures the specific 2.5V full-scale range and mid-scale power-on reset behavior required by the design. Ensure the '#PBF' suffix indicates lead-free compliance as specified in the ordering information.

Selection Notes

Select this part when a quad-channel DAC with 10-bit accuracy and low noise is needed. The 2.5V internal reference simplifies design compared to external reference options. Verify that the 2.7V minimum supply voltage meets system requirements, as the H-grade variant requires a higher minimum voltage for its 4.096V output.

Part Context

This component belongs to the LTC2635 family, which also includes 8-bit and 12-bit variants. The 'L' suffix denotes the 2.5V full-scale version operating from 2.7V to 5.5V, while 'H' denotes the 4.096V version requiring 4.5V to 5.5V. The 'C' grade specifies commercial temperature operation from 0°C to 70°C.
