LTC2630AISC6-LM12#TRMPBF

Overview

The LTC2630AISC6-LM12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. 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 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 ±1 LSB, a typical settling time of 4.4µs at 3V, and a supply current of 180µA at 3V. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V 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.
• Compact Packaging: Housed in a tiny 6-lead SC70 package suitable for space-constrained designs.
• Low Power Consumption: Operates with 180µA supply current at 3V and supports power-down mode reducing current to 1.8µA maximum.

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging option, distinct from the standard 2,500-piece TR configuration. Confirm that the 'I' grade corresponds to the industrial temperature range of –40°C to 85°C and that the 'LM12' designation ensures mid-scale power-on reset behavior with 12-bit resolution.

Selection Notes

Select this component when a single-channel DAC with high DC accuracy (±1 LSB INL) is required in a minimal footprint. The internal 2.5V reference eliminates the need for external components, simplifying board layout. Ensure the application supply voltage falls within the 2.7V to 5.5V range and that the SPI interface timing requirements are met by the host controller.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs available in 12-, 10-, and 8-bit resolutions. The family offers various combinations of accuracy grades, temperature ranges, and power-on reset configurations. The LTC2630A variant specifically denotes the highest accuracy grade with ±1 LSB maximum INL, distinguishing it from standard L or H grade parts which may have higher linearity errors.
