LTC2633HTS8-HI12#TRPBF

Overview

The LTC2633HTS8-HI12#TRPBF is a dual-channel, 12-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 on a single supply voltage ranging from 4.5V to 5.5V. The device communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1.5 LSB, a settling time of 4.7µs at 5V, and a typical supply current of 0.5mA at 5V. It is housed in an 8-lead TSOT-23 package.

Feature Summary

• Dual 12-bit DAC channels with rail-to-rail output buffers
• Integrated 4.096V precision reference with 10ppm/°C drift
• Maximum INL error of ±1.5 LSB for high accuracy
• Power-on reset configured to mid-scale in internal reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive applications

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm that the HI12 designation corresponds to the H-grade temperature range (-40°C to 125°C), 4.096V full-scale output, and mid-scale power-on reset behavior as defined in the manufacturer's selection guide.

Selection Notes

Select this component when a dual-channel DAC with a 4.096V internal reference is required. Ensure the system supply voltage supports the 4.5V to 5.5V operating range specified for the H-grade variant. Verify that the I²C address configuration via the CA0 pin aligns with the system bus requirements.

Part Context

This part belongs to the LTC2633 family of dual DACs. The 'H' suffix denotes the automotive temperature grade (-40°C to 125°C), while 'I' specifies the power-on reset state as mid-scale in internal reference mode. The '12' indicates 12-bit resolution, and 'A' signifies the higher accuracy grade with ±1.5 LSB maximum INL.

Replacement Considerations

Direct replacements within the same family include LTC2633HTS8-LI12#TRPBF for a 2.5V full-scale output or LTC2633HTS8-HZ12#TRPBF for zero-scale power-on reset. Cross-family alternatives like the LTC2635 offer quad channels but differ in package size and pinout.
