LTC2630AHSC6-LM12#TRMPBF

Overview

The LTC2630AHSC6-LM12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 2.5V with a temperature coefficient of 10ppm/°C. The device operates from a single supply voltage ranging from 2.7V to 5.5V and supports a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical settling time of 4.4µs at 3V, and a supply current of 180µA at 3V in internal reference mode.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Maximum INL error of ±1 LSB for the A-grade device
• Power-on reset option set to mid-scale (suffix M)
• Rail-to-rail output buffer with guaranteed monotonicity

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-unit tape and reel packaging configuration as defined in the ordering information section. Confirm that the H temperature grade corresponds to the automotive range of -40°C to 125°C. Ensure the LM12 designation matches the required 2.5V full-scale output and mid-scale power-on reset behavior for the target application design.

Selection Notes

Select this part when a compact 6-lead SC70 footprint is required alongside high accuracy (±1 LSB INL). The H-grade variant is necessary for applications operating between -40°C and 125°C. Choose the LM12 configuration if a fixed 2.5V internal reference and mid-scale initialization are preferred over zero-scale reset or supply-as-reference modes. Verify that the 2.7V minimum supply voltage aligns with the system power rails.

Part Context

This component belongs to the LTC2630 family of single rail-to-rail DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes itself by integrating a low-drift reference into a tiny SC70 package. Variants are categorized by temperature grade (C, I, H), accuracy (standard vs. A-grade), and reset behavior (Zero vs. Mid-scale). This specific part represents the high-temperature, high-accuracy subset of the 12-bit lineup.
