LTC2630ISC6-HM12

Overview

The LTC2630ISC6-HM12 is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference with a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device features a rail-to-rail output buffer, guaranteed monotonicity, and an SPI/Microwire compatible 3-wire serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

• Integrated Precision Reference: Provides a stable 4.096V full-scale output with a temperature coefficient of 10ppm/°C.
• High Accuracy: Guaranteed monotonic operation with a maximum INL error of ±1 LSB for the A-grade device.
• Low Power Consumption: Operates with a typical supply current of 200µA at 5V and supports power-down mode reducing current to 1.8µA maximum.
• Compact Packaging: Housed in a tiny 6-lead SC70 package suitable for space-constrained designs.

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 that the 'I' grade designation matches the required industrial operating temperature range of –40°C to 85°C for the target application environment.

Selection Notes

Select this part when a 12-bit resolution with high linearity (±1 LSB INL) is required in a minimal footprint. Ensure the system supply voltage remains between 4.5V and 5.5V to support the internal 4.096V reference. Consider the power-on reset behavior ('M' suffix for mid-scale) if downstream circuitry requires a defined initial state upon power-up.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes itself by integrating a precision reference into a 6-lead SC70 package. Variants are categorized by accuracy grades (A, C, I, H) and full-scale voltage options (2.5V or 4.096V), allowing designers to balance performance, power, and cost requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Analog Devices marketing for information on non-standard lead-based finish parts or alternative devices within the same product family.
