LTC2630ISC6-HZ10#TRMPBF

Overview

The LTC2630ISC6-HZ10#TRMPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision 4.096V reference with a temperature coefficient of 10ppm/°C and features a rail-to-rail output buffer guaranteed monotonic over temperature. The device operates on a 4.5V to 5.5V supply, consuming 200µA in normal mode and down to 1.8µA in power-down. It utilizes a 3-wire SPI/Microwire interface with clock rates up to 50MHz. Key specifications include ±0.5 LSB DNL, ±0.2 LSB INL, and a settling time of 4.4µs. It is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to zero scale for consistent initialization
• Low power consumption: 200µA active, 1.8µA power-down

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the 'I' grade designation matches the required -40°C to +85°C operating temperature range for the target application environment.

Selection Notes

Select this part when a single-channel DAC with an integrated high-accuracy reference is required in a minimal footprint. The H-grade variant supports a 4.096V full-scale output, requiring a minimum 4.5V supply. Ensure the system can accommodate the 4.5V to 5.5V supply voltage constraints compared to the L-grade 2.7V variants.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes itself by integrating the reference and output buffer into a 6-lead SC70 package, significantly reducing board space compared to discrete solutions or larger packages.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Evaluation of alternative devices requires matching the 10-bit resolution, 4.096V internal reference, SC70-6 package, and compatible SPI interface timing.
