LTC2630AISC6-HZ12#TRMPBF

Overview

The LTC2630AISC6-HZ12#TRMPBF 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 operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a rail-to-rail output buffer and guarantees monotonicity over the specified temperature range. It communicates via a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• 12-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• Power-on reset to zero-scale for consistent initialization

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-piece tape and reel packaging option. Confirm that the 'I' grade designation corresponds to the Industrial temperature range of –40°C to 85°C. Ensure the 'H' code specifies the 4.5V to 5.5V supply requirement for the 4.096V full-scale output. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and lead times.

Selection Notes

Select this component when a high-density, single-channel DAC with an integrated reference is required in an SC70 package. The 'A' grade ensures tighter linearity specifications (±1 LSB INL) compared to standard grades. Choose the 'HZ' configuration if a zero-scale power-on reset state is necessary for system safety or initialization. Verify that the application supply voltage falls within the 4.5V to 5.5V range required for the internal 4.096V reference operation.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family offers various combinations of accuracy grades, temperature ranges, and power-on reset options. The SC70 package provides a small footprint suitable for space-constrained designs. Other variants in the series include different full-scale voltages (2.5V or 4.096V) and mid-scale reset options.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult Analog Devices marketing for information on non-standard lead-based finish parts or alternative packages.
