LTC2630AHSC6-LM12

Overview

The LTC2630AHSC6-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 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 temperature range. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical supply current of 180µA at 3V, and a power-down mode consuming a maximum of 1.8µA. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz.

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.
• Low Power Consumption: Typical supply current of 180µA at 3V; reduces to a maximum of 1.8µA in power-down mode.
• 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 suffix #TRMPBF indicates a 500-piece tape and reel packaging quantity. Confirm the H-grade temperature rating (-40°C to +125°C) aligns with application requirements. Ensure the mid-scale power-on reset configuration matches system initialization needs. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

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 LM suffix indicates a mid-scale power-on reset, which may be preferred if downstream circuits are sensitive to zero-scale outputs during startup. Compare against the LZ variant if a zero-scale reset is necessary. Consider the 2.5V internal reference limitation when designing for higher voltage swings.

Part Context

This part belongs to the LTC2630 family of single 12-/10-/8-bit rail-to-rail DACs with integrated references in SC70 packages. The 'A' denotes the electrical grade with ±1 LSB maximum INL. The 'H' specifies the automotive temperature range (-40°C to +125°C). The 'LM' indicates the mid-scale power-on reset option and 2.5V full-scale voltage. The '#TRMPBF' suffix designates the lead-free, 500-unit tape and reel packaging format.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other members of the LTC2630 family or similar Analog Devices DACs based on pin compatibility and electrical parameter matching.
