LTC2630ISC6-LZ10

Overview

The LTC2630ISC6-LZ10 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 2.5V and operates from a single 2.7V to 5.5V supply. The device guarantees monotonicity over temperature and includes a power-on reset circuit that clears the output to zero scale upon initialization. It utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 3.9µs at 3V, and a typical supply current of 200µA.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Power-on reset to zero scale for consistent system initialization
• Rail-to-rail output buffer with guaranteed monotonicity
• Low power operation: 200µA supply current, 1.8µA max in power-down

Applications

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

Procurement Notes

Verify the specific suffixes against the manufacturer's ordering information to ensure correct resolution, temperature grade, and power-on reset behavior. Confirm RoHS compliance status and lead-free designator requirements for the target assembly process. Check for any designated sales channel restrictions regarding tape and reel quantities if non-standard packaging is required.

Selection Notes

Select this component when a compact 10-bit DAC with an internal 2.5V reference is required in space-constrained designs. The 'I' grade ensures operation across the industrial temperature range of –40°C to 85°C. Choose the 'LZ' suffix if a zero-scale power-on reset is necessary to prevent unintended outputs during system startup. Ensure the supply voltage remains within the 2.7V to 5.5V range for specified performance.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family shares a common 6-lead SC70 package and SPI-compatible interface but varies by temperature grade (C, I, H), full-scale voltage (2.5V or 4.096V), and power-on reset configuration (zero or mid-scale). The ISC6-LZ10 variant specifically targets industrial applications requiring low-power, space-efficient signal generation.
