LTC2635CUD-LMI8#TRPBF

Overview

The LTC2635CUD-LMI8#TRPBF is a quad 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 16-lead 3mm × 3mm QFN package. It features an integrated precision reference providing a 2.5V full-scale output with a temperature coefficient of 10ppm/°C. The device operates on a single 2.7V to 5.5V supply and includes rail-to-rail output buffers guaranteed monotonic over the commercial temperature range of 0°C to 70°C. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes, with power-on reset options set to mid-scale.

Feature Summary

Quad 8-Bit Resolution with Integrated 2.5V Reference
I²C Interface with Standard and Fast Mode Support
Rail-to-Rail Output Buffers Guaranteed Monotonic
Power-On Reset to Mid-Scale in Internal Reference Mode

Applications

Mobile Communications
Process Control and Industrial Automation
Portable Equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates lead-free construction and tape-and-reel packaging containing 2,500 pieces. Confirm the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C for the application environment.

Selection Notes

Select this component when four independent 8-bit DAC channels are required in a compact QFN footprint. The internal 2.5V reference simplifies design by eliminating external reference components. Ensure the system supply voltage falls within the 2.7V to 5.5V range compatible with the LTC2635-L series specifications.

Part Context

This part belongs to the LTC2635 family of quad DACs, which also offers 10-bit and 12-bit resolutions. The 'L' suffix denotes the 2.5V full-scale variant powered by a low-voltage supply, while the 'UD' package code specifies the 16-pin QFN form factor. The 'Z' power-on reset option resets outputs to zero-scale, whereas 'MI' sets them to mid-scale upon initialization.
