LTC2630HSC6-HM8#TRMPBF

Overview

The LTC2630HSC6-HM8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates double-buffered data latches and power-on reset functionality set to mid-scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer capable of sourcing/sinking up to 10mA
• Selectable power-on reset to zero or mid-scale output
• Low power consumption: 200µA operating current, 5µA in power-down mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive sensor interfaces

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration as defined in the ordering information. Confirm that the H-grade temperature rating (-40°C to +125°C) aligns with the target application environment requirements. Ensure the 4.5V minimum supply voltage constraint is met by the system power rail design.

Selection Notes

Select this part when a compact SC70-6 package is required for space-constrained designs. Choose the HM8 variant specifically for applications needing mid-scale power-on reset behavior rather than zero-scale. Verify that the 8-bit resolution meets the system accuracy needs, as higher resolution options like the 12-bit variants are available within the same family.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. The 'H' designation specifies the automotive temperature grade (-40°C to +125°C), while 'M' indicates the mid-scale power-on reset option. The '8' denotes 8-bit resolution, and 'SC6' refers to the 6-lead SC70 plastic package. This specific part number represents a high-reliability variant suitable for demanding industrial environments.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630HSC6-LM8#TRMPBF (2.5V reference) or LTC2630HSC6-HZ8#TRMPBF (zero-scale reset). Cross-family replacements require verification of interface compatibility and reference voltage alignment.
