LTC2630HSC6-LM10#TRMPBF

Overview

The LTC2630HSC6-LM10#TRMPBF is a single-channel, 10-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 rail-to-rail output buffer and supports SPI/MICROWIRE compatible 3-wire serial interfaces with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.4µs at 5V, and a typical supply current of 200µA. It incorporates power-on reset functionality set to mid-scale and double-buffered data latches.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• SPI/MICROWIRE compatible 3-wire serial interface supporting up to 50MHz clock
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• Power-on reset to mid-scale with double-buffered data latches

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 compatibility with the required 4.5V to 5.5V supply voltage constraints for specified performance.

Selection Notes

Select this part when a 10-bit resolution is sufficient for the application, offering lower power consumption compared to 12-bit variants. The LM suffix indicates a mid-scale power-on reset state, suitable for systems where downstream circuits are active during initialization. Verify that the system supply voltage remains within the 4.5V to 5.5V range required for the H-series internal reference operation.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The H-series specifically denotes devices with a 4.096V full-scale output derived from an internal reference, requiring a minimum supply voltage of 4.5V. The SC70-6 package provides a compact footprint for space-constrained designs.

Replacement Considerations

Direct replacements within the same family include LTC2630HSC6-HZ10#TRMPBF (zero-scale reset) or LTC2630HSC6-HM12#TRMPBF (12-bit resolution). Cross-family alternatives such as the LTC2631 series offer I2C interfaces but require different pinout considerations.
