LTC2630CSC6-HZ10#TRPBF

Overview

The LTC2630CSC6-HZ10#TRPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision 4.096V reference with a 10ppm/°C temperature coefficient and a rail-to-rail output buffer in a compact 6-lead SC70 package. The device operates on a 4.5V to 5.5V supply and features a 3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.4µs at 5V, and a typical supply current of 200µA. It includes power-on reset options and double-buffered data latches.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• 3-wire SPI/MICROWIRE serial interface with 50MHz clock rate
• Power-on reset to zero scale (HZ suffix)
• Double-buffered data latches for glitch-free updates

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging format containing 2,500 pieces. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to 70°C. Ensure the 'H' designation matches the required 4.5V to 5.5V supply voltage operation and 4.096V full-scale output. Cross-reference the 'Z' suffix to confirm the power-on reset behavior is set to zero scale rather than mid-scale.

Selection Notes

Select this component when a single-channel DAC with high density in an SC70 package is required. Choose the HZ10 variant specifically for applications needing a 4.096V internal reference, 10-bit resolution, and a zero-scale power-on reset state. Verify that the system supply voltage remains within the 4.5V to 5.5V range specified for the H-grade devices. Consider the 200µA supply current if low power consumption is a critical design constraint.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares the same 6-lead SC70 footprint and pinout, allowing for pin-compatible upgrades or downgrades based on resolution needs. Variants differ by full-scale voltage (2.5V for L-grade, 4.096V for H-grade), power-on reset behavior (M for mid-scale, Z for zero-scale), and accuracy grades (A vs standard).

Replacement Considerations

Direct pin-compatible replacements within the same package include other LTC2630 variants such as LTC2630CSC6-LZ10#TRPBF (2.5V ref) or LTC2630CSC6-HM10#TRPBF (mid-scale reset). For different channel counts, the LTC2634 (quad) or LTC2635 (quad) series offer similar performance but require larger packages.
