LTC2630HSC6-LM12

Overview

The LTC2630HSC6-LM12 is a single-channel, 12-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 rail-to-rail output buffer and communicates via a 3-wire SPI/Microwire compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±2 LSB, a typical settling time of 4.4µs at 5V, and a supply current of 190µA in internal reference mode. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

• Integrated Precision Reference: Provides a stable 4.096V full-scale output with a temperature coefficient of 10ppm/°C.
• High Accuracy: Guaranteed monotonic operation with a maximum INL error of ±2 LSB for the standard grade.
• Low Power Consumption: Typical supply current of 190µA at 3V and 200µA at 5V; power-down mode reduces current to 5µA maximum.
• Compact Packaging: Available in a tiny 6-lead SC70 package suitable for space-constrained designs.

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-piece tape and reel packaging option. Confirm that the H-grade designation ensures operation across the automotive temperature range of –40°C to +125°C. Ensure the LM suffix is selected if mid-scale power-on reset behavior is required for system initialization.

Selection Notes

Select this part when a 4.096V full-scale range is needed with a minimum supply voltage of 4.5V. Choose the H-grade for extended temperature coverage up to 125°C. The LM suffix provides a mid-scale reset on power-up, whereas the LZ suffix resets to zero scale. Verify compatibility with 3-wire SPI or Microwire host controllers operating at frequencies up to 50MHz.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. Variants are distinguished by resolution (8, 10, or 12 bits), full-scale voltage (2.5V for L-grade, 4.096V for H-grade), and power-on reset state (Mid-Scale 'M' or Zero-Scale 'Z'). The HSC6-LM12 specifically denotes the H-grade, SC70 package, Mid-Scale reset, and 12-bit resolution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices marketing for information on non-standard lead-based finish parts or alternative devices within the broader DAC portfolio.
