LTC2630CSC6-LM12#TRMPBF

Overview

The LTC2630CSC6-LM12#TRMPBF 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 on a single supply voltage ranging from 2.7V to 5.5V. The device incorporates a rail-to-rail output buffer and is guaranteed monotonic over the operating temperature range. It utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical parameters include a maximum integral nonlinearity (INL) error of ±2 LSB for standard grades, a typical settling time of 4.4µs at 3V, and a supply current of 190µA. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated Precision Reference: Provides a fixed 2.5V full-scale output with a low drift of 10ppm/°C.
• Rail-to-Rail Output Buffer: Ensures full output swing capability with guaranteed monotonicity across the temperature range.
• Low Power Consumption: Operates with a typical supply current of 180µA at 3V and supports power-down mode with maximum current of 1.8µA.
• Flexible Serial Interface: Compatible with SPI and MICROWIRE protocols, supporting clock frequencies up to 50MHz.

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration, distinct from the standard 2,500-piece reel (#TRM). Confirm that the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C for the target application environment.

Selection Notes

Select this part when a single-channel DAC with a 2.5V internal reference limit is required in a minimal footprint. The LM suffix configures the device for a mid-scale power-on reset state; choose the LZ suffix if a zero-scale reset is preferred. Ensure the system supply voltage remains within the 2.7V to 5.5V range specified for the LTC2630-L series.

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 6-lead SC70 package and core architecture but varies by accuracy grade (A vs. standard), temperature rating (C, I, H), and full-scale voltage configuration (L for 2.5V, H for 4.096V).

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Analog Devices marketing or technical support for cross-reference information regarding alternative components.
