LTC2637HDE-HZ8#PBF

Digital To Analog Converters Overview

The LTC2637HDE-HZ8#PBF is an octal 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a 4.096V full-scale output and operates on a single 4.5V to 5.5V supply. The device communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C temperature range, and a power-on reset circuit configured to zero-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
• Rail-to-rail buffered outputs with ultralow crosstalk (<3nV•s)
• I2C interface with selectable slave addresses via CA0 pin

Digital To Analog Converters Applications

• Process control and industrial automation systems
• Portable battery-powered equipment
• Automotive electronic modules
• Optical networking signal conditioning

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix HZ8#PBF against official documentation to confirm the package type, temperature grade, and power-on reset behavior. Ensure compatibility with system voltage requirements of 4.5V to 5.5V before procurement.

Digital To Analog Converters Selection Notes

Select this component for applications requiring multiple low-resolution voltage outputs with high channel density. The H-grade ensures operation up to 125°C. Verify that the I2C bus speed and address configuration meet system constraints.

Digital To Analog Converters Part Context

This part belongs to the LTC2637 family, which offers 8-, 10-, and 12-bit resolutions. The 'H' designation indicates automotive-grade performance (-40°C to 125°C), while 'DE' specifies the 14-lead DFN package. The 'Z8' suffix denotes 8-bit resolution with zero-scale power-on reset.

Digital To Analog Converters Replacement Considerations

LTC2637IDE-HZ8#PBF: Industrial temperature grade (-40°C to 85°C). LTC2637CMS-HZ8#PBF: Commercial temperature grade (0°C to 70°C). LTC2637HMS-HZ8#PBF: Same electrical specs but in 16-lead MSOP package.
