LTC2630AHSC6-LZ12

Overview

The LTC2630AHSC6-LZ12 is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 6-lead SC70 package. It features an integrated precision reference providing a 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.4µs at 3V, and low power consumption of 180µA at 3V. It incorporates double-buffered data latches and offers power-on reset options to zero or mid-scale.

Feature Summary

• 12-Bit Resolution with ±1 LSB Maximum INL
• Integrated 2.5V Precision Reference (10ppm/°C)
• Rail-to-Rail Output Buffer with Guaranteed Monotonicity
• 3-Wire SPI/MICROWIRE Serial Interface (Up to 50MHz)

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel quantity. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to 70°C. Ensure the 'A' electrical grade matches the requirement for ±1 LSB maximum INL. Check RoHS compliance status as specified in the manufacturer's documentation.

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 state is necessary for system initialization. The A-grade variant is suitable for applications demanding high linearity accuracy (±1 LSB). Consider the H-grade variants if a 4.096V full-scale output or extended temperature range is needed.

Part Context

This part belongs to the LTC2630 family of single-channel DACs. Other members include the LTC2630CSC6 and LTC2630ISC6 series, which differ primarily in temperature grades (Commercial and Industrial). Variants such as LTC2630AHSC6-HM12 offer different full-scale voltages (4.096V) and power-on reset behaviors (Mid-Scale). The family shares identical pinouts and serial interface protocols.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Direct replacements within the same family include LTC2630CSC6-LZ12#TRMPBF (Commercial grade) or LTC2630ISC6-LZ12#TRMPBF (Industrial grade), assuming temperature requirements align.
