LTC2637CMS-LMX12#TRPBF

Overview

The LTC2637CMS-LMX12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a selectable internal or external reference, with the 'L' suffix indicating a 2.5V full-scale output and operation on a single 2.7V to 5.5V supply. The device communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches and a power-on reset circuit configured to reset to mid-scale in external reference mode. The component is housed in a 16-lead MSOP package.

Feature Summary

Octal architecture with 12-bit resolution per channel
I2C-compatible serial interface with selectable address pins
Power-on reset to mid-scale for external reference mode
Rail-to-rail output buffers guaranteed monotonic over temperature

Applications

Mobile communications
Process control and industrial automation
Automatic test equipment
Portable equipment
Automotive systems

Procurement Notes

Verify the specific ordering suffix LMX12#TRPBF against official documentation to confirm the mid-scale reset behavior in external reference mode and the tape-and-reel packaging quantity. Ensure the design supports the required I2C clock rates and supply voltage range of 2.7V to 5.5V for the LTC2637-L variant.

Selection Notes

Select this part when an octal DAC configuration is required with 12-bit precision and I2C connectivity. The L-series designation restricts operation to a 2.7V to 5.5V supply range with a 2.5V full-scale output. Consider the H-series if a 4.5V to 5.5V supply and 4.096V full-scale are needed. Verify that the MSOP package fits the board space constraints.

Part Context

This component belongs to the LTC2637 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The family offers choices between DFN and MSOP packages and various temperature grades. The CMS suffix indicates the Industrial temperature grade (-40°C to 85°C), while the L suffix specifies the low-voltage 2.5V full-scale variant.
