LTC2630CSC6-HM10

Overview

The LTC2630CSC6-HM10 is a single-channel, 10-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 is guaranteed monotonic over temperature. It communicates via a simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.4µs at 5V, and a typical supply current of 200µA in internal reference mode.

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 ±1 LSB for the 10-bit resolution.
• Low Power Consumption: Typical supply current of 200µA at 5V; power-down mode reduces current to 1.8µA 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 #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the 'HM' designation corresponds to the Mid-Scale power-on reset option and the 'H' grade ensures operation within the 4.5V to 5.5V supply range. Ensure compatibility with the required commercial temperature range if applicable, though this part number typically denotes the H-grade automotive range (-40°C to 125°C).

Selection Notes

Select this component when a single-channel DAC with a fixed 4.096V internal reference is required in a minimal footprint. The HM suffix is critical for applications needing a mid-scale output upon power-up rather than zero-scale. Ensure the system supply voltage remains between 4.5V and 5.5V to meet specified performance parameters. Consider the 10-bit resolution if 12-bit accuracy is not necessary to optimize cost and power.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares the same SC70 package and SPI interface but varies by resolution, reset behavior (Mid-Scale vs. Zero), and full-scale voltage options (2.5V or 4.096V). The LTC2630CSC6-HM10 specifically combines the 10-bit resolution with the 4.096V reference and mid-scale reset feature.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630CSC6-HZ10#TRPBF (Zero-scale reset) and LTC2630CSC6-HM12#TRPBF (12-bit resolution). Verify that the alternative part's reset behavior and resolution meet the system requirements before substitution.
