LTC2630HSC6-LM10

Overview

The LTC2630HSC6-LM10 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 monotonicity, and a power-on reset circuit that defaults to mid-scale. Communication is handled via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.4µs at 5V, and a typical supply current of 200µA.

Feature Summary

• Integrated 4.096V Precision Reference with 10ppm/°C drift
• Rail-to-Rail Output Buffer with Guaranteed Monotonicity
• Power-On Reset to Mid-Scale (Suffix M)
• 3-Wire SPI/MICROWIRE Interface with 50MHz Clock Rate

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's official documentation to confirm temperature grade, resolution, and reset configuration. Ensure the supply voltage range meets the 4.5V to 5.5V requirement for the H-grade internal reference variant. Confirm lead-free compliance and tape-and-reel packaging specifications if applicable.

Selection Notes

Select this component when a compact 10-bit DAC with a fixed 4.096V full-scale range is required in a minimal footprint. The H-suffix indicates operation from 4.5V to 5.5V supplies. The M-suffix ensures the output initializes to mid-scale upon power-up, which may be necessary for downstream circuit protection or initialization sequences compared to zero-scale options.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes between L-grade (2.5V FS, 2.7V–5.5V supply) and H-grade (4.096V FS, 4.5V–5.5V supply) variants. The SC70 package provides a small form factor suitable for space-constrained designs, differentiating it from larger QFN or MSOP packages found in quad-channel counterparts like the LTC2634 or LTC2635.
