LTC2630ISC6-LM10

Overview

The LTC2630ISC6-LM10 is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference yielding a 2.5V full-scale output and operates within a 2.7V to 5.5V supply range. The device features a rail-to-rail output buffer, SPI/MICROWIRE compatible 3-wire serial interface, and double-buffered data latches. Key electrical parameters include a maximum integral nonlinearity of ±1 LSB, settling time of 3.9µs at 3V, and supply current of 180µA. It incorporates power-on reset to mid-scale and is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• SPI/MICROWIRE compatible 3-wire serial interface up to 50MHz
• Power-on reset to mid-scale option

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature grade, resolution, and packaging configuration. Ensure compatibility with system requirements for supply voltage range and serial interface timing before procurement.

Selection Notes

Select this component for applications requiring high integration in space-constrained designs. The LM suffix indicates a mid-scale power-on reset, suitable for systems where downstream circuits are active during initialization. Verify that the 2.5V internal reference aligns with the required output span.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes itself by offering multiple accuracy grades and reset options within a standard 6-lead SC70 package, providing flexibility for various embedded signal chain requirements.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630ISC6-LZ10 (zero-scale reset) or LTC2630ISC6-HM10 (4.096V full-scale). Verify that the alternative part's power-on reset behavior and full-scale voltage meet the system design specifications.
