LTC2630CSC6-LM10

Overview

The LTC2630CSC6-LM10 is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It integrates a precision 2.5V reference with a 10ppm/°C temperature coefficient and a rail-to-rail output buffer. The device operates on a single supply ranging from 2.7V to 5.5V and features a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 3.9µs at 3V, and a typical supply current of 180µA. The part includes power-on reset circuitry configured to initialize the output to mid-scale.

Feature Summary

• 10-Bit Resolution with Integrated 2.5V Precision Reference
• Rail-to-Rail Output Buffer with Guaranteed Monotonicity
• 3-Wire Serial Interface (SPI/MICROWIRE) Operating up to 50MHz
• Power-On Reset to Mid-Scale Configuration

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Portable Equipment

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout compatibility and lead finish specifications. Ensure the selected temperature grade matches the operational environment requirements. Confirm that the SC70 package dimensions align with the target PCB footprint constraints before finalizing procurement.

Selection Notes

Select this component when a compact 10-bit DAC with an integrated reference is required for space-constrained designs. The LM suffix indicates a mid-scale power-on reset, which is suitable for systems where downstream circuits must remain active during initialization. Verify that the 2.5V full-scale output range meets the input requirements of the subsequent analog stages.

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 integrating high-accuracy references into a tiny 6-lead SC70 package. Variants are categorized by resolution, reset behavior (Zero or Mid-Scale), and full-scale voltage options (2.5V or 4.096V).
