LTC2630AHSC6-HM12#TRPBF

Digital To Analog Converters 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.

Digital To Analog Converters 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.

Digital To Analog Converters 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.

Digital To Analog Converters 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.

Digital To Analog Converters 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.

Digital To Analog Converters 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.
