LTC2630ISC6-HZ8

Digital To Analog Converters Overview

The LTC2630ISC6-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 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical characteristics 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 incorporates double-buffered data latches and a power-on reset circuit configured to clear the output to zero scale upon initialization.

Digital To Analog Converters Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• Power-on reset to zero scale for consistent system initialization
• Low power operation: 200µA typical supply current; 1.8µA max in power-down mode

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix HZ8 confirms the 8-bit resolution, 4.096V full-scale internal reference, and zero-scale power-on reset configuration. Confirm the ISC6 designation indicates the Industrial temperature grade (-40°C to +85°C) and SC-70-6 package. Ensure compatibility with the required 4.5V to 5.5V supply voltage range for specified performance.

Digital To Analog Converters Selection Notes

Select this part when an 8-bit resolution is sufficient for the application, offering higher speed and lower power compared to 12-bit variants. The HZ suffix is critical for applications requiring a defined zero-volt state immediately after power-up. Verify that the 4.096V full-scale range aligns with downstream input requirements. The SC-70 package is suitable for space-constrained designs.

Digital To Analog Converters Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common 6-lead SC-70 footprint and SPI interface but varies by resolution, full-scale voltage (2.5V or 4.096V), and power-on reset behavior (Zero or Mid-Scale). The 'I' grade denotes industrial temperature operation, distinguishing it from Commercial (C) and Automotive (H) grades.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same package and interface include other LTC2630 variants such as LTC2630ISC6-HM8#TRPBF (Mid-Scale reset) or LTC2630ISC6-LZ8#TRPBF (2.5V Full Scale). Cross-family replacements like the LTC2631 require verification of pinout and register compatibility.
