LTC2630HSC6-HZ12#TRPBF

Overview

The LTC2630HSC6-HZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and a temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a rail-to-rail output buffer guaranteed monotonic over temperature. Communication is handled via a simple SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. It includes a power-on reset circuit that defaults to zero-scale output.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• SPI/MICROWIRE compatible 3-wire serial interface
• Power-on reset to zero-scale option

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging configuration as defined in the manufacturer's documentation. Confirm the H-grade designation matches the required automotive temperature range of –40°C to 125°C for the intended application environment.

Selection Notes

Select this part when a compact 6-lead SC70 package is required alongside high accuracy (±1 LSB INL for A-grade variants, though standard H-grade specifies ±2 LSB). Ensure the system supply voltage remains between 4.5V and 5.5V to support the 4.096V full-scale output. Consider the power-down current specifications if low standby power consumption is critical.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. The 'H' indicates the automotive temperature grade (-40°C to 125°C), 'SC6' denotes the 6-lead SC70 package, 'HZ' signifies the 4.096V full-scale internal reference with zero-scale power-on reset, and '12' represents the 12-bit resolution.

Replacement Considerations

Direct replacements within the same family include LTC2630HSC6-LZ12#TRPBF (2.5V full-scale) or LTC2630HSC6-HM12#TRPBF (mid-scale reset). Cross-family alternatives like the LTC2631 require I2C interfaces and different pinouts.
