LTC2630HSC6-HZ8#TRMPBF

Overview

The LTC2630HSC6-HZ8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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 rail-to-rail output buffer and communicates via a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) error of ±2 LSB, a settling time of 3.7µs at 5V, and a typical supply current of 200µA. The part incorporates a power-on reset circuit configured to clear the output to zero scale upon initialization.

Feature Summary

• Integrated Precision Reference: Provides a stable 4.096V full-scale output with a temperature coefficient of 10ppm/°C.
• Rail-to-Rail Output Buffer: Ensures guaranteed monotonicity over the operating temperature range (-40°C to 125°C).
• Power-On Reset to Zero-Scale: Automatically clears the DAC output to zero code upon power-up for consistent system initialization.
• Compact Packaging: Housed in a tiny 6-lead SC70 package to minimize PCB footprint.

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel configuration. Confirm that the H-grade designation aligns with the required automotive temperature range of -40°C to 125°C. Ensure the HZ suffix matches the design requirement for zero-scale power-on reset behavior rather than mid-scale reset options available in other variants.

Selection Notes

Select this component when a compact, low-power 8-bit DAC is required with a fixed 4.096V internal reference. The HZ variant is appropriate for systems requiring a known zero-state output immediately after power application. Verify that the 4.5V minimum supply voltage constraint fits the system's power architecture, as lower voltage operation requires the L-series variants.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The HSC6 designation identifies the specific combination of the Automotive temperature grade (H), the 6-lead SC70 package, and the 8-bit resolution. Other family members vary by resolution, reset behavior (M vs Z), and full-scale voltage options (L vs H series).

Replacement Considerations

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