LTC2630HSC6-HZ12#TRMPBF

Overview

The LTC2630HSC6-HZ12#TRMPBF 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 simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) error of ±2 LSB, a typical settling time of 4.8µs at 12-bit accuracy, and low power consumption of 200µA. It incorporates a power-on reset circuit that defaults to zero-scale output.

Feature Summary

• Integrated high-accuracy reference with 10ppm/°C drift for 4.096V full-scale output
• Rail-to-rail output buffer guaranteed monotonic over temperature
• Power-on reset to zero-scale for consistent system initialization
• Low power operation: 200µA active current, 1.8µA maximum in power-down mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the SC70 package type matches the target PCB footprint requirements. Cross-reference the datasheet revision date against manufacturing lot codes for compliance verification.

Selection Notes

Select this part when a compact 6-lead SC70 package is required alongside a fixed 4.096V internal reference. Choose the HZ variant specifically if a zero-scale power-on reset state is necessary for safety or initialization logic. Compare against the HM variant if mid-scale reset is preferred. Verify that the 4.5V minimum supply voltage aligns with the system's available rail, as the L-grade variants support lower voltages down to 2.7V.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. The 'H' suffix denotes the automotive temperature grade (-40°C to 125°C), while 'HZ' specifies the zero-scale power-on reset behavior. The '12' indicates 12-bit resolution, and 'SC6' identifies the 6-lead SC70 plastic package. The '#TRMPBF' suffix confirms lead-free construction and a 500-unit tape and reel shipping format.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should evaluate other members of the LTC2630 family, such as the LTC2630HSC6-HM12#TRMPBF, noting differences in power-on reset behavior (mid-scale vs. zero-scale). Alternative packages like the SOT-23-6 may require schematic and layout modifications.
