LTC2630HSC6-HM8

Overview

The LTC2630HSC6-HM8 is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a rail-to-rail output buffer and supports SPI/MICROWIRE compatible 3-wire serial interfaces with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±0.5 LSB, a typical settling time of 3.7µs at 5V, and a supply current of 180µA. It incorporates power-on reset functionality set to mid-scale and is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to mid-scale configuration
• Low power consumption: 180µA operating current, 1.8µA power-down

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging format. Confirm the temperature grade 'H' corresponds to the automotive range of -40°C to +125°C. Ensure the pinout matches the standard 6-lead SC70 configuration for PCB layout compatibility.

Selection Notes

Select this component when a compact footprint is required alongside moderate resolution. The 8-bit resolution offers ±0.5 LSB INL accuracy suitable for general-purpose control loops. Verify that the system supply voltage remains within the 4.5V to 5.5V window required for the H-grade internal reference operation.

Part Context

This part belongs to the LTC2630 family of DACs, which differentiates itself by integrating high-accuracy references into a tiny SC70 package. The 'H' designation specifically denotes the automotive temperature grade (-40°C to 125°C) and the 4.096V full-scale output capability derived from the internal reference architecture.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630HSC6-LM8 (2.5V FS, commercial temp) or LTC2630HSC6-HZ8 (zero-scale reset). Cross-family replacements require verification of interface compatibility and voltage headroom.
