LTC2630HSC6-LZ10#TRMPBF

Overview

The LTC2630HSC6-LZ10#TRMPBF 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 simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical characteristics 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. The part is housed in a compact 6-lead SC70 package and includes power-on reset functionality that defaults the output to zero scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• SPI/MICROWIRE compatible 3-wire serial interface supporting up to 50MHz clock
• Power-on reset option to zero scale for consistent system initialization
• Rail-to-rail output buffer with guaranteed monotonicity over temperature

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging quantity, distinct from the standard 2,500-unit reel. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to +125°C. Ensure the LZ suffix confirms the zero-scale power-on reset behavior required by the application design.

Selection Notes

Select this component when a 4.096V full-scale output is required with a minimum supply voltage of 4.5V. The H-grade temperature rating is necessary for environments exceeding 85°C. Choose the LZ variant if the system requires the DAC output to initialize at zero volts upon power-up rather than mid-scale. Verify that the 10-bit resolution meets the system accuracy requirements while minimizing power consumption.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The 'H' prefix denotes the high-voltage/full-scale variant (4.096V) requiring a 4.5V–5.5V supply, whereas the 'L' variant provides 2.5V full-scale. The 'SC6' indicates the 6-lead SC70 plastic package. The 'LZ' combination specifies the zero-scale power-on reset feature, distinguishing it from the 'LM' mid-scale reset option.

Replacement Considerations

Direct replacements within the same family include LTC2630HSC6-HM10#TRMPBF for mid-scale reset or LTC2630HSC6-LZ12#TRMPBF for higher resolution. Cross-family alternatives require matching the 10-bit resolution, 4.096V reference, and SC70 package constraints.
