LTC2630AHSC6-HZ12#TRMPBF

Overview

The LTC2630AHSC6-HZ12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference with a temperature coefficient of 10ppm/°C and operates in a 6-lead SC70 package. This specific variant features an H-grade automotive temperature rating (-40°C to +125°C), a maximum Integral Nonlinearity (INL) of ±1 LSB, and a power-on reset function that clears the output to zero scale. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for data transfer.

Feature Summary

• Integrated precision reference providing a full-scale output of 4.096V
• Automotive grade temperature range: -40°C to +125°C
• Maximum INL error guaranteed at ±1 LSB for 12-bit resolution
• Power-on reset circuit configured to clear output to zero scale

Applications

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

Procurement Notes

Verify the H-grade suffix indicates the specified -40°C to +125°C operating range. Confirm the Z suffix corresponds to the zero-scale power-on reset behavior. Ensure the TRMPBF designation matches the required 500-unit tape and reel packaging format for procurement planning.

Selection Notes

Select this part when a compact 6-lead SC70 footprint is required alongside high linearity accuracy. The H-grade temperature rating makes it suitable for harsh automotive environments. Choose this over L-grade variants if the application requires a 4.096V full-scale output rather than 2.5V.

Part Context

This component belongs to the LTC2630 family of rail-to-rail DACs. The 'A' suffix denotes the electrical grade with tighter linearity specifications compared to standard parts. The 'H' indicates the extended temperature capability, while 'Z' specifies the initial output state upon power-up.

Replacement Considerations

Direct replacements within the same package and specification include other LTC2630 variants such as the LTC2630HSC6-HZ12#TRMPBF or LTC2630HSC6-HM12#TRMPBF, provided the power-on reset requirement (Zero vs Mid-Scale) aligns with the system design.
