LTC2637HMS-LMI8#TRPBF

Digital To Analog Converters Overview

The LTC2637HMS-LMI8#TRPBF is an octal 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches, rail-to-rail output buffers guaranteed monotonic over the -40°C to 125°C temperature range, and a power-on reset circuit configured to initialize outputs to mid-scale in internal reference mode.

Digital To Analog Converters Feature Summary

• Octal architecture with 8 independent 8-bit DAC channels
• Integrated 4.096V precision reference with ±10ppm/°C drift
• I2C-compatible serial interface with selectable slave addresses
• Power-on reset to mid-scale in internal reference mode

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the H-grade designation ensures operation within the automotive temperature range of -40°C to 125°C. Ensure the MS package corresponds to the 16-lead MSOP form factor required for the design.

Digital To Analog Converters Selection Notes

Select this part when eight isolated voltage outputs are required with high accuracy and low crosstalk. The H-grade variant is necessary for applications requiring operation up to 125°C junction temperature. The LMI suffix specifies the internal power-on reset behavior to mid-scale, which differs from the LZ (zero-scale) or LMX (external reference) options.

Digital To Analog Converters Part Context

This component belongs to the LTC2637 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The H-series variants are distinguished by their higher full-scale output voltage of 4.096V compared to the L-series 2.5V output. The MS package denotes the 16-lead Mini Small Outline Package, offering a compact footprint suitable for dense PCB layouts.

Digital To Analog Converters Replacement Considerations

Direct functional equivalents within the same family include LTC2637HMS-LZ8#TRPBF (zero-scale reset) and LTC2637HMS-LMX8#TRPBF (external reference reset). For different resolutions, consider LTC2637HMS-LMI10#TRPBF or LTC2637HMS-LMI12#TRPBF, noting that pin compatibility remains consistent across the resolution variants.
