LTC2630AISC6-HZ12#TRPBF

Overview

The LTC2630AISC6-HZ12#TRPBF is a single-channel, 12-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 specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

• 12-Bit Resolution with ±1 LSB Maximum INL
• Integrated Precision Reference (4.096V Full-Scale)
• Rail-to-Rail Output Buffer
• SPI/MICROWIRE Compatible 3-Wire Serial Interface

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive

Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging configuration as defined in the manufacturer's documentation. Confirm that the H-grade temperature rating (-40°C to +125°C) meets the operational requirements for the intended environment. Ensure compatibility with the 4.5V to 5.5V supply voltage range specified for the H-series devices.

Selection Notes

Select this component when a compact 6-lead SC70 package is required alongside high accuracy (±1 LSB INL). The H-grade variant is necessary for applications requiring operation up to 125°C or utilizing the 4.096V internal reference. Compare against L-grade variants if a lower supply voltage (2.7V–5.5V) or 2.5V full-scale output is preferred. Consider the power-down current specifications if low standby power is critical.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs. The 'A' designation indicates the highest accuracy grade with ±1 LSB maximum INL. The 'H' suffix denotes the automotive/extended temperature grade (-40°C to 125°C) and the 4.5V–5.5V supply requirement. The 'Z' indicates a power-on reset to zero-scale, while 'M' would indicate mid-scale reset.

Replacement Considerations

Direct pin-compatible replacements within the same series include LTC2630HSC6-HZ12#TRPBF (standard accuracy) or LTC2630HSC6-HM12#TRPBF (mid-scale reset). For lower temperature ranges, consider the I-grade equivalents such as LTC2630ISC6-HZ12#TRPBF.
