LTC2630HSC6-LM8

Overview

The Analog Devices LTC2630HSC6-LM8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. The device includes a rail-to-rail output buffer, guaranteed monotonicity, and double-buffered data latches. It communicates via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Power-on reset options include mid-scale initialization, and the part supports power-down mode for low current consumption.

Feature Summary

• Integrated 10ppm/°C precision reference with 2.5V full-scale output
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• 3-wire SPI/MICROWIRE compatible serial interface operating up to 50MHz
• Power-on reset to mid-scale option with low power-down current

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration as defined in the ordering information. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to +125°C. Ensure the LM suffix is correctly interpreted as the mid-scale power-on reset setting. Cross-reference the SC6 package code with the physical 6-lead SC70 footprint requirements.

Selection Notes

Select this model for applications requiring an 8-bit resolution DAC in a minimal footprint. The LM suffix designates a mid-scale power-on reset state; choose the LZ suffix if a zero-scale reset is required instead. The L-series designation ensures compatibility with 2.7V to 5.5V supply voltages. Verify that the 8-bit resolution meets system accuracy needs, as higher precision variants like the LTC2630A offer ±1 LSB INL.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family shares common architectural features including the SC70 package, SPI interface, and integrated reference options. The specific HSC6-LM8 variant combines the high-temperature grade, SC70 package, mid-scale reset, and 8-bit resolution within this product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should verify pinout and electrical compatibility when considering alternative manufacturers' 8-bit DACs in SC70 packages.
