LTC2630CSC6-HZ8#TRPBF

Overview

The LTC2630CSC6-HZ8#TRPBF 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 specifications include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 3.7µs at 5V, and a typical supply current of 180µA. It incorporates double-buffered data latches and power-on reset functionality to zero scale.

Feature Summary

• Integrated 4.096V Precision Reference: Provides stable full-scale output with 10ppm/°C drift in internal reference mode.
• High-Speed Serial Interface: Supports 3-wire SPI/MICROWIRE communication with SCK frequencies up to 50MHz.
• Rail-to-Rail Output Buffer: Capable of sourcing/sinking up to 10mA at 5V with guaranteed monotonicity.
• Power-Down Mode: Reduces supply current to a maximum of 1.8µA for power-constrained applications.

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm that the H-grade temperature rating (-40°C to 125°C) aligns with the target operating environment requirements. Ensure the 4.5V minimum supply voltage constraint is met by the system power rails.

Selection Notes

Select this part when a compact SC70-6 package is required alongside an integrated high-voltage reference. The 8-bit resolution is suitable for applications where cost and pin count are prioritized over high precision. Verify compatibility with the host microcontroller's SPI timing constraints, specifically setup and hold times relative to the 50MHz clock capability.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The 'H' designation specifies the automotive temperature grade (-40°C to 125°C), while 'Z' indicates a power-on reset to zero scale. The 'SC6' package denotes the 6-lead SC70 form factor, distinguishing it from larger packages like MSOP or QFN found in other variants.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Cross-referencing should focus on matching the 8-bit resolution, 4.096V internal reference, SC70-6 package, and -40°C to 125°C operating temperature range.
