LTC2630HSC6-LZ8

Overview

The LTC2630HSC6-LZ8 is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 2.5V and operates on a single supply ranging from 2.7V to 5.5V. The device incorporates rail-to-rail output buffers and is guaranteed monotonic over the operating temperature range. Communication is handled via a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. A power-on reset circuit ensures outputs initialize to zero scale upon power-up.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• 3-wire SPI/MICROWIRE serial interface with 50MHz clock rate
• Power-on reset to zero scale for consistent initialization

Applications

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

Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering information guide to confirm package type, temperature grade, and power-on reset behavior. Ensure compatibility with system voltage requirements, as the L-grade variant requires a minimum of 2.7V. Confirm lead-free compliance and tape-and-reel specifications if applicable for automated assembly processes.

Selection Notes

Select this component when a compact 6-lead SC70 package is required for space-constrained designs. Choose the LZ suffix if a zero-scale power-on reset is necessary to prevent downstream circuit activation during startup. Consider the H-grade variant if operation above 85°C or higher full-scale voltage (4.096V) is needed, noting the increased minimum supply voltage requirement.

Part Context

This part belongs to the LTC2630 family of single-channel DACs. The 'L' designation indicates a 2.5V internal reference and a 2.7V–5.5V supply range. The 'Z' suffix specifies a power-on reset to zero scale. The 'SC6' denotes the 6-lead SC70 plastic package. Other variants in the family include different resolutions (8-bit, 10-bit), mid-scale reset options ('M'), and automotive temperature grades ('H').

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630HSC6-LM8, LTC2630HSC6-LZ10, and LTC2630HSC6-HZ12. Verify that the substitute part matches the required resolution, power-on reset state, and operating temperature range before implementation.
