LTC2630HSC6-LZ8#TRPBF

Overview

The LTC2630HSC6-LZ8#TRPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with 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 supporting clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 4.8µs at 12-bit accuracy, and a typical supply current of 200µA. It incorporates a power-on reset circuit configured to clear the output to zero scale upon initialization.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• Power-on reset to zero scale for consistent system initialization
• Low power operation: 200µA typical supply current

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF against manufacturer documentation to confirm tape and reel packaging specifications. Ensure the H-grade automotive temperature rating (-40°C to +125°C) aligns with environmental requirements. Confirm that the LZ8 designation correctly specifies the 8-bit resolution, 4.096V full-scale output, and zero-scale power-on reset configuration.

Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy needs. The H-grade variant is required for automotive or high-temperature environments operating between -40°C and +125°C. The internal 4.096V reference eliminates the need for external components if this voltage level matches the system requirement. Verify that the 4.5V minimum supply voltage is compatible with the available power rails.

Part Context

This part belongs to the LTC2630 family of single-channel DACs housed in a compact 6-lead SC70 package. The family offers various combinations of resolution (8, 10, or 12 bits), full-scale voltages (2.5V or 4.096V), and power-on reset behaviors. The 'H' suffix denotes the extended automotive temperature grade, while 'LZ' indicates the zero-scale reset and 4.096V full-scale configuration.
