LTC2636CDE-LMX12#TRPBF

Overview

The LTC2636CDE-LMX12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) in a 14-lead DFN package. It features an integrated 10ppm/°C reference with a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over –40°C to 125°C, and a 3-wire SPI/MICROWIRE interface supporting clock rates up to 50MHz. Power-on reset defaults to mid-scale in external reference mode. Supply current is typically 0.9mA at 3V.

Feature Summary

Octal 12-bit DACs with integrated 10ppm/°C reference
2.5V full-scale output range with 2.7V to 5.5V supply operation
SPI/MICROWIRE compatible 3-wire serial interface up to 50MHz
Power-on reset to mid-scale in external reference mode

Applications

Mobile Communications
Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment
Automotive
Optical Networking

Procurement Notes

Verify the specific ordering suffix LMX12 confirms mid-scale power-on reset in external reference mode and 12-bit resolution. Confirm the DE suffix indicates the 14-lead DFN package. Ensure the C grade matches the required commercial temperature range of 0°C to 70°C. Check that TRPBF denotes tape and reel packaging with lead-free composition.

Selection Notes

Select this part for applications requiring eight independent 12-bit channels with high accuracy. The L suffix provides a 2.5V full-scale range suitable for lower voltage systems. The MX suffix sets the power-on state to mid-scale when using an external reference. The C grade is appropriate for commercial environments within 0°C to 70°C. Consider the MSOP package if hardware clear and LDAC pins are required.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), power-on reset behavior, and package type. The LMX12 variant specifically combines 12-bit resolution, 2.5V internal reference scaling, and mid-scale external reference reset behavior.
