LTC2630CSC6-HZ8

Overview

The LTC2630CSC6-HZ8 is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a rail-to-rail output buffer and communicates via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) error of ±2 LSB, a typical settling time of 3.7µs at 5V, and power consumption of approximately 180µA. The unit incorporates a power-on reset circuit that defaults the output to zero scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to zero scale for consistent initialization
• Compact 6-lead SC70 package

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 packaging configuration. Confirm the temperature grade corresponds to the H-grade specification (-40°C to 125°C). Ensure compatibility with the required 4.5V to 5.5V supply voltage range before procurement.

Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy requirements. The HZ suffix designates a 4.096V full-scale output with a zero-scale power-on reset. This part is suitable for space-constrained designs requiring a small SC70 footprint and low power consumption in automotive or industrial environments.

Part Context

The LTC2630 family includes various combinations of resolution (8-, 10-, 12-bit), reset behavior (M for mid-scale, Z for zero-scale), and reference voltages (L for 2.5V, H for 4.096V). The CSC6 designation identifies the commercial temperature grade (0°C to 70°C) in the standard part numbering system, though the H suffix in the model name typically denotes the automotive temperature grade (-40°C to 125°C).

Replacement Considerations

Direct replacements within the same family include LTC2630CSC6-HZ10#TRMPBF (10-bit) and LTC2630CSC6-HZ12#TRMPBF (12-bit) if higher resolution is needed. For different reset behaviors, consider LTC2630CSC6-HM8 variants.
