LTC2630ISC6-HZ8#TRPBF

Overview

The LTC2630ISC6-HZ8#TRPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference and rail-to-rail output buffer within a compact 6-lead SC70 package. The device operates with a supply voltage range of 4.5V to 5.5V, providing a full-scale output of 4.096V in internal reference mode. It features a 3-wire SPI/Microwire compatible serial interface supporting 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 power-on reset function that clears the output to zero scale upon initialization.

Feature Summary

• Integrated 10ppm/°C precision reference with 4.096V full-scale output
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to zero scale for consistent system initialization
• Low power consumption: 200µA typical supply current

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm the temperature grade 'I' corresponds to the industrial range of –40°C to 85°C. Ensure compatibility with the required 4.5V to 5.5V supply voltage constraints before procurement.

Selection Notes

Select this part when an 8-bit resolution is sufficient for the application, offering lower cost compared to 10- or 12-bit variants. The H-grade designation requires a minimum supply voltage of 4.5V. Choose this model if a zero-scale power-on reset state is required to prevent transient outputs during system startup.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common SC70 footprint and SPI interface but varies in accuracy, full-scale voltage options (2.5V or 4.096V), and power-on reset behaviors. The ISC6 variant specifically denotes the Industrial temperature grade and SC70 package type.

Replacement Considerations

Direct replacements within the same family include LTC2630ISC6-HZ10#TRPBF (10-bit) or LTC2630ISC6-HZ12#TRPBF (12-bit) if higher resolution is needed. For different reset behaviors, consider the HM suffix for mid-scale reset. Verify pinout and software command compatibility when substituting.
