LTC2630ISC6-HZ10

Overview

The LTC2630ISC6-HZ10 is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference yielding a 4.096V full-scale output and operates within a 4.5V to 5.5V supply range. The device features a rail-to-rail output buffer, SPI/MICROWIRE compatible 3-wire serial interface, and double-buffered data latches. Key electrical parameters include a maximum integral nonlinearity of ±1 LSB, settling time of 4.4µs at 3V (4.4µs typical for 10-bit), and power consumption of 180µA at 3V with internal reference. It supports power-down mode with current draw as low as 1.8µA.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• SPI/MICROWIRE compatible 3-wire serial interface up to 50MHz
• Power-on reset to zero-scale option

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-unit tape and reel packaging configuration. Confirm the 'I' grade corresponds to the -40°C to 85°C industrial temperature range. Ensure the ordering code matches the required resolution (10-bit) and reset behavior (Zero-scale). Cross-reference the manufacturer's official documentation for lead-free compliance and RoHS status.

Selection Notes

Select this component when a compact 6-lead SC70 package is required for space-constrained designs. Choose the H-grade variant if the system requires a 4.096V full-scale output rather than 2.5V. Verify that the application can support the 4.5V minimum supply voltage requirement. Consider the power-down feature for battery-operated devices requiring ultra-low standby current.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares identical pinouts and interfaces but varies in accuracy, full-scale voltage options (2.5V or 4.096V), and power-on reset behaviors. The ISC6 designation specifies the Industrial temperature grade and SC70-6 package type.

Replacement Considerations

Direct pin-compatible replacements within the same family include other LTC2630 variants with different resolutions or reset settings. For multi-channel applications, consider the LTC2634 (Quad) or LTC2635 (Quad I2C) families, noting the interface difference for the latter.
