LTC2630HSC6-LZ8#TRMPBF

Overview

The LTC2630HSC6-LZ8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated precision reference with 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 specifications include a maximum integral nonlinearity (INL) error of ±2 LSB, guaranteed monotonicity over the operating temperature range, and a power-on reset function that clears the output to zero scale. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to zero scale for consistent initialization
• 3-wire SPI/MICROWIRE serial interface supporting up to 50MHz

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel configuration as defined in the manufacturer's order information. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the L suffix matches the 4.096V full-scale specification and the Z suffix confirms the zero-scale power-on reset behavior required by the system design.

Selection Notes

Select this part when a single-channel DAC with high accuracy in a minimal footprint is required. The H-grade variant is suitable for applications demanding operation up to 125°C. The 8-bit resolution provides a balance between cost and performance for applications not requiring 12-bit precision. Consider the 4.096V internal reference if external reference components are undesirable or if supply voltage regulation is sufficient for alternative modes.

Part Context

This component belongs to the LTC2630 family of rail-to-rail DACs, which also includes 10-bit and 12-bit variants (LTC2630-10, LTC2630-12). The family shares the same 6-lead SC70 package and core architecture but differs in resolution, linearity specifications, and available full-scale voltages. The LTC2630 series is designed to replace larger packages while maintaining performance comparable to older generation multi-pin DACs.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should verify pin compatibility and electrical parameters against existing solutions, noting that the SC70 package and 3-wire interface are specific to this family.
