LTC2630CSC6-LZ12#TRMPBF

Overview

The LTC2630CSC6-LZ12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and operates on a single supply voltage ranging from 2.7V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±2 LSB, a settling time of 4.4µs at 3V, and a typical supply current of 180µA. It incorporates a power-on reset circuit that defaults to zero scale.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• Power-on reset to zero scale for consistent system initialization
• Low power consumption: 180µA operating current, 1.8µA max in power-down mode

Applications

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

Procurement Notes

Verify the component matches the specific package type (6-lead SC70) and temperature grade (Commercial, 0°C to 70°C). Confirm the ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging quantity as specified in the manufacturer's documentation. Ensure compatibility with the required 2.7V to 5.5V supply range and 3-wire serial interface protocol.

Selection Notes

Select this part when a compact 12-bit DAC with an internal 2.5V reference is required in a small SC70 package. Choose the 'L' variant for operation down to 2.7V, whereas the 'H' variant requires a minimum of 4.5V. The 'Z' suffix ensures the output resets to zero upon power-up, which is critical for applications where downstream circuits must remain inactive during startup. Verify that the ±2 LSB INL specification meets the application's accuracy requirements.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common pinout and serial interface but varies in resolution, full-scale voltage options (2.5V or 4.096V), and power-on reset behavior. The LTC2630 series is designed to replace larger packages by integrating the reference and amplifier into a 6-lead SC70 footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should evaluate other members of the LTC2630 family (e.g., LTC2630CSC6-HZ12#TRMPBF for 4.096V full scale) or similar Analog Devices DACs based on specific voltage and accuracy needs.
