LTC2630AHSC6-HM12#TRMPBF

Overview

The LTC2630AHSC6-HM12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference with a 10ppm/°C temperature coefficient and operates in a 6-lead SC70 package. The device features a rail-to-rail output buffer and supports an SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a typical settling time of 4.8µs at 5V, and a supply current of 200µA. It requires a 4.5V to 5.5V supply range and functions within an operating temperature of -40°C to +125°C.

Feature Summary

• Integrated precision reference providing a 4.096V full-scale output with 10ppm/°C drift
• Maximum INL error of ±1 LSB for high accuracy applications
• Rail-to-rail output buffer capable of driving capacitive loads up to 500pF
• Power-on reset option configured to mid-scale via the 'M' suffix

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics

Procurement Notes

Verify that the H-grade designation confirms the -40°C to +125°C automotive temperature range and the HM suffix ensures the mid-scale power-on reset state. Confirm the #TRMPBF suffix indicates a 500-unit tape and reel packaging quantity, as standard reels contain 2,500 units. Ensure the 4.5V minimum supply requirement aligns with the system design.

Selection Notes

Select this part when a compact 6-lead SC70 footprint is required alongside high linearity (±1 LSB INL). The H-grade is necessary for environments exceeding 85°C. Choose the HM variant over HZ if a mid-scale initialization is preferred upon power-up. Verify that the 4.5V to 5.5V supply constraint fits the available power rails.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. The specific ordering suffixes define its unique configuration: 'H' denotes the automotive temperature grade and 4.096V reference, 'M' sets the power-on reset to mid-scale, and '12' specifies 12-bit resolution. Other variants exist with different resolutions, reset states, and commercial temperature grades.
