LTC2630HSC6-HZ10

Overview

The LTC2630HSC6-HZ10 is a single-channel, 10-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 4.096V and operates from a single 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. It utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical parameters include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.4µs at 5V, and a power-down current of 5µA maximum for the H-grade automotive variant.

Feature Summary

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

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging option. Confirm the H-grade designation aligns with the required -40°C to 125°C operating temperature range for the target application environment. Ensure the 4.5V minimum supply voltage requirement is met by the system design.

Selection Notes

Select this component when a compact 6-lead SC70 footprint is required alongside a high-accuracy internal reference. The HZ10 suffix specifies a 10-bit resolution, 4.096V full-scale output, and zero-scale power-on reset behavior. Consider the H-grade temperature rating if operation exceeds the industrial limit of 85°C. Verify that the 50Ω typical channel resistance at the rails meets the load regulation requirements for the specific application current.

Part Context

This part belongs to the LTC2630 family of single-channel DACs. Variants within the family differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), power-on reset state (mid-scale or zero-scale), and temperature grade (C, I, or H). The HSC6-HZ10 specifically denotes the Automotive grade, SC70 package, Zero-scale reset, and 10-bit resolution configuration.

Replacement Considerations

Direct pin-compatible replacements within the same package and interface include other LTC2630 variants such as LTC2630ISC6-HZ10#TRMPBF (Industrial grade) or LTC2630CSC6-HZ10#TRMPBF (Commercial grade). For higher resolution needs, the LTC2630A series offers ±1 LSB INL performance. Multi-channel alternatives like the LTC2635 require different packages and interfaces.
