LTC2630HSC6-HZ8

Overview

The LTC2630HSC6-HZ8 is a single-channel, 8-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 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) error of ±0.5 LSB, a settling time of 3.7µs at 5V, and a typical supply current of 180µA. It incorporates a power-on reset circuit that defaults the output to zero scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• Power-on reset to zero scale for consistent system initialization
• Low power operation: 180µA typical supply current

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific suffix HZ8 corresponds to the 8-bit resolution, 4.096V full-scale, and zero-scale power-on reset configuration as defined in the ordering information. Confirm the SC70 package type and automotive temperature grade (-40°C to 125°C) match the application requirements. Check for RoHS compliance status and lead-free designator markings on the shipping container.

Selection Notes

Select this component when a compact, single-channel DAC with high accuracy is required in space-constrained designs. The HZ8 variant is suitable for applications needing a guaranteed zero-state output upon power-up. Ensure the system supply voltage remains between 4.5V and 5.5V to meet specified performance parameters. Consider the 3-wire serial interface compatibility with the host microcontroller's SPI or Microwire protocol.

Part Context

This part belongs to the LTC2630 family of single rail-to-rail DACs available in a 6-lead SC70 package. The family offers various combinations of resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset options (zero or mid-scale). The HZ8 specifically denotes the 8-bit resolution, 4.096V internal reference, and zero-scale reset configuration.

Replacement Considerations

Direct replacements within the same family include other LTC2630 variants with different resolutions or reset configurations, such as LTC2630HSC6-HM8 (mid-scale reset) or LTC2630HSC6-HZ10 (10-bit resolution). Verify pinout compatibility and electrical parameter overlaps before substitution.
