LTC2630HSC6-HM10

Overview

The LTC2630HSC6-HM10 is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 4.096V and operates from a 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key electrical parameters include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.4µs at 5V, and a typical supply current of 200µA.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• 3-wire serial interface supporting up to 50MHz clock
• Power-on reset to mid-scale

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific suffix 'H' for the automotive temperature grade (-40°C to 125°C) and 'HM' for mid-scale power-on reset against design requirements. Confirm the SC70 package footprint matches the PCB layout. Ensure the supply voltage range supports the 4.5V minimum required for the H-grade internal reference operation.

Selection Notes

Select this component when a compact single-channel DAC with high accuracy is needed. The H-grade variant is suitable for harsh environments requiring -40°C to 125°C operation. Choose between HM (mid-scale reset) or HZ (zero-scale reset) based on system initialization safety needs. Verify that the 4.5V to 5.5V supply constraint fits the target application power rails.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares the same SC70 package and core architecture but varies in accuracy grades (A vs standard), resolution, and power-on reset behavior. The H-suffix denotes the extended temperature range compared to C (Commercial) and I (Industrial) grades.

Replacement Considerations

Direct pin-compatible replacements within the same package include other LTC2630 variants such as LTC2630ISC6-HZ10#TRPBF (12-bit, zero-reset) or LTC2630ISC6-LM10#TRPBF (10-bit, 2.5V ref). Cross-family replacements like the LTC2634 require different packages and interfaces.
