LTC2630CSC6-LZ12

Overview

The LTC2630CSC6-LZ12 is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision 2.5V reference with a 10ppm/°C temperature coefficient and operates on a single 2.7V to 5.5V supply. The device features rail-to-rail output buffers, guaranteed monotonicity, and a maximum integral nonlinearity (INL) of ±2 LSB. It communicates via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. The part includes a power-on reset circuit that defaults to zero-scale output and is housed in a compact 6-lead SC70 package.

Feature Summary

• 12-bit resolution with integrated 2.5V precision reference (10ppm/°C)
• Rail-to-rail output buffer with ±2 LSB maximum INL
• 3-wire SPI/MICROWIRE serial interface operating up to 50MHz
• Power-on reset to zero-scale with low power consumption (180µA at 3V)

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm the C-grade temperature range (0°C to 70°C) aligns with system requirements. Ensure the LZ suffix correctly specifies the zero-scale power-on reset behavior for the design.

Selection Notes

Select this component when a single-channel DAC with high accuracy in a minimal footprint is required. The LZ suffix ensures the output initializes to zero upon power-up, which is critical for safety or initialization-sensitive downstream circuits. Verify that the 2.5V full-scale range meets the application's voltage span needs.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common 6-lead SC70 package and SPI interface architecture. Variations within the family differ by resolution, full-scale voltage options (2.5V or 4.096V), and power-on reset states.

Replacement Considerations

Direct pin-compatible replacements within the same family include other LTC2630 variants such as LTC2630CSC6-HZ12#TRMPBF (4.096V FS) or LTC2630CSC6-LM12#TRMPBF (mid-scale reset). Cross-family replacements require verification of interface compatibility and package dimensions.
