LTC2630HSC6-LZ12

Overview

The LTC2630HSC6-LZ12 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 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) error of ±2 LSB, a settling time of 4.8µs at 5V, and power consumption of 280µA in normal mode. It incorporates a power-on reset circuit that defaults the output to zero scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer capable of sourcing/sinking up to 10mA
• Power-on reset to zero scale for consistent system initialization
• Compact 6-lead SC70 package design

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm the H-grade temperature rating (-40°C to 125°C) matches the operational environment requirements. Ensure the 4.5V minimum supply voltage aligns with the system power rails.

Selection Notes

Select this part when a compact footprint is required alongside high accuracy. The LZ suffix ensures the output initializes to zero upon power-up, which is critical for safety-sensitive applications. Compare against the LM variant if mid-scale initialization is preferred instead.

Part Context

This component belongs to the LTC2630 family of rail-to-rail DACs. The 'H' designation specifies the automotive temperature grade, while 'LZ' defines the internal reference voltage (4.096V) and the zero-scale power-on reset behavior. It serves as a space-efficient solution for multi-channel systems requiring precise analog control.

Replacement Considerations

Direct functional replacements within the same package and specification profile include other variants from the LTC2630 family, such as the LTC2630HSC6-HZ12 or LTC2630HSC6-LZ12, depending on the required power-on reset state.
