LTC2630ISC6-HM8#TRPBF

Overview

The LTC2630ISC6-HM8#TRPBF is a single-channel, 8-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 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer, guaranteed monotonicity, and a power-on reset circuit that initializes the output to mid-scale. Communication is handled via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical parameters 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: Provides stable full-scale output with 10ppm/°C drift without external components.
• Rail-to-Rail Output Buffer: Delivers analog voltage across the entire supply range with guaranteed load regulation.
• Power-On Reset to Mid-Scale: Ensures predictable system initialization by setting the output to mid-scale upon power-up.
• High-Speed Serial Interface: Supports SPI/MICROWIRE protocols with SCK frequencies up to 50MHz for rapid data transfer.

Applications

• Process Control and Industrial Automation
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix #TRPBF indicates a tape and reel packaging quantity of 2,500 pieces. Confirm the 'I' grade designation matches the required industrial temperature range of –40°C to 85°C. Ensure the 'HM' code corresponds to the 4.096V full-scale voltage and mid-scale power-on reset configuration. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and lead times.

Selection Notes

Select this component when a compact 8-bit DAC is required with a fixed 4.096V output range. The HM suffix is critical for designs needing a mid-scale power-on state rather than zero-scale. Verify that the system supply voltage remains within the 4.5V to 5.5V window to ensure specified performance. Consider the 6-lead SC70 package constraints for PCB layout and thermal management in space-sensitive applications.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The ISC6 variant specifically denotes the Industrial temperature grade (-40°C to 85°C) and the SC70-6 plastic package. The HM10 suffix in related datasheet examples indicates a 10-bit resolution with similar voltage and reset characteristics, highlighting the modular nature of the product line based on resolution and reset behavior.

Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2630ISC6-HZ8#TRPBF, which offers the same 8-bit resolution and 4.096V range but resets to zero-scale instead of mid-scale. Other options involve adjusting resolution or voltage ranges, such as the LTC2630ISC6-LM8 series for 2.5V outputs.
