LTC2630AHSC6-HM12#TRPBF

Overview

The LTC2630AHSC6-HM12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference with a temperature coefficient of 10ppm/°C and a rail-to-rail output buffer in a compact 6-lead SC70 package. The device operates within a supply voltage range of 4.5V to 5.5V, providing a full-scale output of 4.096V when using the internal reference. It features a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.8µs at 5V, and an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated Precision Reference: Provides a stable 4.096V full-scale output with a low drift of 10ppm/°C.
• High Accuracy: Guaranteed monotonicity with a maximum INL error of ±1 LSB for the A-grade device.
• Compact Packaging: Available in a space-saving 6-lead SC70 package suitable for portable applications.
• Flexible Interface: Supports standard 3-wire SPI and Microwire protocols with clock speeds up to 50MHz.

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify that the H suffix corresponds to the required 4.5V–5.5V supply range and 4.096V full-scale output. Confirm the HM suffix indicates the power-on reset behavior sets the output to mid-scale. Ensure the SC6 package matches the PCB footprint requirements. Check RoHS compliance status if necessary for specific manufacturing standards.

Selection Notes

Select this part when a single-channel DAC with high accuracy (±1 LSB INL) and automotive temperature rating (-40°C to +125°C) is required. Choose the HM variant over HZ if a mid-scale power-on reset is preferred for system initialization. Consider the L or I grade variants if lower cost or different temperature ranges are acceptable, noting they may have higher INL errors.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. The 'A' denotes the electrical grade with ±1 LSB max INL. The 'H' specifies the 4.5V–5.5V supply range and 4.096V internal reference. The 'M' indicates a power-on reset to mid-scale. The '12' designates 12-bit resolution. The '#TRPBF' suffix indicates tape and reel packaging without lead-free designation changes affecting function.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Other members of the LTC2630 family, such as the LTC2630ISC6-HM12#TRMPBF, offer similar functionality but differ in temperature grade (Industrial vs. Automotive) and potentially linearity specifications.
