LTC2630ISC6-HM8#TRMPBF

Overview

The LTC2630ISC6-HM8#TRMPBF is a single-channel, 8-bit rail-to-rail voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference with a full-scale output of 4.096V and operates on a 4.5V to 5.5V supply. The device features a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 4.4µs at 5V, and a typical supply current of 200µA. It is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer capable of sourcing/sinking up to 10mA
• 3-wire serial interface (SPI/MICROWIRE) with 50MHz clock capability
• Power-on reset to mid-scale for consistent initialization

Applications

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

Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration as specified in the ordering information. Confirm that the system power supply remains within the 4.5V to 5.5V range required for the HM grade full-scale voltage. Ensure the design accounts for the industrial temperature range (-40°C to 85°C) associated with the 'I' designation.

Selection Notes

Select this component when a compact 8-bit resolution is sufficient for applications requiring a fixed 4.096V output span. The HM variant requires a minimum supply voltage of 4.5V, unlike the LM variant which supports 2.7V. Consider the power-down mode for low-power applications, which reduces current consumption to a maximum of 1.8µA. Verify compatibility with the host microcontroller's SPI timing constraints.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The 'H' suffix denotes the 4.096V full-scale version powered by an internal reference, while 'M' indicates a power-on reset to mid-scale. The 'SC6' package identifies the 6-lead SC70 form factor, providing high board density for space-constrained designs.
