LTC2630CSC6-HZ8#TRMPBF

Overview

The LTC2630CSC6-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 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) error of ±0.5 LSB, guaranteed monotonicity, and a power-on reset function that clears the output to zero scale. It is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated Precision Reference: Provides a stable 4.096V full-scale output with a temperature coefficient of 10ppm/°C.
• High Accuracy: Delivers a maximum INL error of ±0.5 LSB and guaranteed monotonic operation over the operating temperature range.
• Zero-Scale Power-On Reset: Automatically resets the DAC output to zero upon power-up for consistent system initialization.
• Low Power Consumption: Operates with a typical supply current of 200µA at 5V and supports power-down mode with current consumption as low as 5µA.

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the ordering information matches the exact part number to guarantee the correct resolution, reset state, and package type.

Selection Notes

Select this component when a compact 8-bit DAC with a fixed 4.096V internal reference is required. The HZ suffix ensures a zero-scale power-on reset, which is critical for systems where downstream circuits must remain inactive during startup. Verify that the supply voltage remains within the 4.5V to 5.5V range to meet specified performance parameters.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs available in 12-, 10-, and 8-bit resolutions. The CSC6 identifier denotes the commercial temperature grade (0°C to 70°C) combined with the SC70 package, while the HZ suffix specifies the 4.096V full-scale voltage and zero-scale reset behavior. The family shares a common pinout and serial interface architecture across different accuracy grades.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical parameter alignment if considering alternative manufacturers' devices.
