LTC2636CMS-LMX10#TRPBF

Overview

The LTC2636CMS-LMX10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated high-accuracy reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 2.5V in internal reference mode. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches and guarantees monotonicity over the commercial temperature range of 0°C to 70°C.

Feature Summary

• Octal architecture with 8 independent 10-bit DAC channels
• Integrated 10ppm/°C reference yielding 2.5V full-scale output
• SPI/MICROWIRE compatible 3-wire serial interface operating at 50MHz
• Power-on reset configured for mid-scale output in external reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics
• Optical networking devices

Procurement Notes

Verify that the specific suffix LMX10 corresponds to the required power-on reset behavior (mid-scale in external reference mode) and resolution. Confirm package type MSOP-16 matches the design footprint. Ensure the commercial temperature grade (0°C to 70°C) meets system environmental requirements. Check datasheet for lead-free compliance details associated with the #PBF designation.

Selection Notes

Select this part when eight low-cost, moderate-resolution DACs are needed with integrated references. The LMX suffix indicates mid-scale reset in external reference mode; choose LZ10 for zero-scale or LMI10 for mid-scale in internal reference mode if those behaviors are preferred. Verify supply voltage constraints, as the -L variant supports 2.7V to 5.5V, whereas the -H variant requires 4.5V to 5.5V.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. Variants include the LTC2636DE (DFN package) and LTC2636MS (MSOP package). Other series members like the LTC2637 offer I2C interfaces instead of SPI. The -L suffix denotes the 2.5V full-scale version, while -H denotes the 4.096V version.
