LTC2637HMS-HMX12#TRPBF

Overview

The LTC2637HMS-HMX12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a 4.096V full-scale output, operating on a 4.5V to 5.5V supply. The device communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity error of ±2.5 LSB, low noise of 0.75mVP-P (0.1Hz to 200kHz), and ultralow DAC-to-DAC crosstalk below 3nV•s. It incorporates double-buffered data latches and power-on reset functionality.

Feature Summary

Octal architecture with 12-bit resolution and rail-to-rail output buffers
Integrated 4.096V precision reference with 10ppm/°C drift
Ultralow crosstalk between DAC channels (<3nV•s)
I2C interface with selectable internal or external reference modes

Applications

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

Procurement Notes

Verify the H-grade temperature rating (-40°C to 125°C) and MSOP-16 package configuration against design requirements. Confirm the MX suffix indicates mid-scale reset in external reference mode if external references are utilized. Ensure supply voltage constraints (4.5V to 5.5V) align with system power rails before procurement.

Selection Notes

Select this component for applications requiring multiple synchronized voltage outputs with high accuracy. The H-grade variant supports wider temperature ranges than C or I grades. Consider the MSOP-16 package for space-constrained designs where DFN options are unsuitable. Verify that the 4.096V full-scale range meets the downstream circuit input requirements.

Part Context

This part belongs to the LTC2637 family of octal DACs. The 'H' suffix denotes the automotive temperature grade (-40°C to 125°C). The 'MX' suffix specifies power-on reset behavior to mid-scale when using an external reference. The '12' indicates 12-bit resolution, and 'MS' identifies the 16-lead MSOP package.
