LTC2630ACSC6-LZ12#TRPBF

Overview

The LTC2630ACSC6-LZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 2.5V and operates within a supply voltage range of 2.7V to 5.5V. The device incorporates a rail-to-rail output buffer and guarantees monotonicity over the operating temperature range. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB for the A-grade device, a typical supply current of 180µA at 3V with the internal reference active, and a power-down mode current of 1.8µA maximum. It utilizes a 3-wire SPI/Microwire compatible serial interface.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V full-scale output with a temperature coefficient of 10ppm/°C.
• High Accuracy: A-grade specification ensures a maximum Integral Nonlinearity (INL) error of ±1 LSB across the full temperature range.
• Low Power Consumption: Typical supply current is 180µA at 3V; power-down mode reduces current to a maximum of 1.8µA.
• Compact Packaging: Available 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 ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging configuration as defined in the manufacturer's order information. Confirm that the C-grade temperature rating (0°C to 70°C) aligns with the intended operational environment requirements before procurement.

Selection Notes

Select this component when a single-channel DAC with high accuracy (±1 LSB INL) and low power consumption is required in a minimal footprint. Ensure the application supply voltage falls within the 2.7V to 5.5V range compatible with the 'L' variant. Verify that the zero-scale power-on reset behavior meets system initialization needs, as mid-scale options are available in other part numbers.

Part Context

This part belongs to the LTC2630 family of single-channel DACs, which offers various combinations of resolution (8-, 10-, or 12-bit), accuracy grades, and temperature ranges. The 'A' designation indicates the highest accuracy grade with ±1 LSB INL, while 'C' denotes the commercial temperature range. The 'LZ12' suffix specifies the 2.5V internal reference, zero-scale power-on reset, and 12-bit resolution.

Replacement Considerations

Direct replacements within the same family include LTC2630ACSC6-HZ12#TRPBF (4.096V reference) or LTC2630ACSC6-LM12#TRPBF (mid-scale reset). Cross-family replacements require verification of pin compatibility and performance parameters against the original datasheet specifications.
