LTC2630CSC6-HZ10

Overview

The LTC2630CSC6-HZ10 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 specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, guaranteed monotonicity over temperature, 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 4.096V precision reference with 10ppm/°C drift
• SPI/MICROWIRE compatible 3-wire serial interface supporting up to 50MHz clock
• Power-on reset to zero scale for consistent system initialization
• Rail-to-rail output buffer with guaranteed monotonicity

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 against the manufacturer's official documentation to confirm lead finish and tape/reel specifications. Ensure the selected temperature grade matches the operational environment requirements. Cross-reference part markings with the product selection guide to validate resolution and reset configuration.

Selection Notes

Select this component when a single-channel DAC with high accuracy and minimal board space is required. The H-grade variant supports a wider supply range starting at 4.5V compared to the L-grade. Consider the power-on reset behavior; the Z-suffix ensures a zero-scale output upon power-up, which is critical for applications where downstream circuits must remain inactive during initialization.

Part Context

This device belongs to the LTC2630 family of rail-to-rail DACs available in 8-, 10-, and 12-bit resolutions. The family offers combinations of internal reference voltages (2.5V or 4.096V) and power-on reset options (zero or mid-scale). All variants share the same 6-lead SC70 package and serial interface architecture, differing primarily in resolution, reference voltage, and reset state.

Replacement Considerations

Direct replacements within the same family include LTC2630CSC6-LZ10 (2.5V reference) or LTC2630CSC6-HM10 (mid-scale reset). For higher resolution needs, consider the LTC2630CSC6-HZ12. Ensure any substitute maintains the 4.5V minimum supply requirement if using the 4.096V reference mode.
