LTC2630AHSC6-LZ12#TRPBF

Overview

The Analog Devices LTC2630AHSC6-LZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 2.5V with a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.4µs at 3V, and a typical supply current of 180µA. The part includes double-buffered data latches and power-on reset options.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V full-scale output with a low drift of 10ppm/°C.
• High Accuracy: Guaranteed monotonic operation with a maximum INL error of ±1 LSB for the A-grade device.
• Compact Packaging: Available in a tiny 6-lead SC70 surface-mount package suitable for space-constrained designs.
• Simplified Interface: Communicates via a standard 3-wire SPI/Microwire serial interface with clock speeds up to 50MHz.

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel quantity, distinct from the standard 2,500-unit #TRPBF configuration. Confirm that the 'A' grade designation ensures the tighter ±1 LSB INL specification compared to standard grades. Ensure the SC70 package type matches the PCB footprint requirements for the 6-lead plastic SC70 outline.

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. The 2.5V internal reference suits applications where the output range does not require the 4.096V span offered by the H-grade variants. The LZ suffix configures the power-on reset state to zero-scale, which is critical for systems requiring a known safe initial output condition upon power-up.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs. The 'A' denotes the electrical grade with ±1 LSB max INL, 'H' indicates the automotive temperature range (-40°C to 125°C), 'SC6' specifies the 6-lead SC70 package, 'L' sets the 2.5V full-scale reference, 'Z' enables power-on reset to zero-scale, and '12' defines the 12-bit resolution.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing SPI controllers if replacing similar parts from other manufacturers, as pinouts and command codes may differ.
