LTC2630HSC6-LM12#TRPBF

Overview

The LTC2630HSC6-LM12#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 and operates from a single 2.7V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. Key electrical parameters include a maximum integral nonlinearity (INL) of ±2 LSB for the standard grade, a typical supply current of 180µA at 3V with internal reference, and a power-down current of 1.8µA maximum. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to mid-scale code
• Low power operation: 180µA active, 1.8µA power-down

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm the H-grade temperature range (-40°C to 125°C) matches application requirements. Ensure the LM12 designation aligns with the need for mid-scale power-on reset and 2.5V full-scale output. Cross-reference the manufacturer's latest ordering information for lead-free compliance details.

Selection Notes

Select this part when a compact 12-bit DAC with an integrated 2.5V reference is required in an SC70 package. Choose the H-grade variant for automotive or high-temperature environments (-40°C to 125°C). Opt for the LM suffix if system initialization requires a mid-scale output upon power-up rather than zero-scale. Consider the 180µA supply current for battery-powered applications.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), power-on reset behavior (Zero or Mid-scale), and temperature grade (C, I, or H). The HSC6-LM12 specifically denotes the H-grade, SC70 package, mid-scale reset, and 12-bit resolution.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630HSC6-HM12 (4.096V FS) or LTC2630HSC6-LZ12 (Zero-scale reset). Verify that the alternative part's full-scale voltage and reset state meet the system design constraints before substitution.
