LTC2633HTS8-HI10#TRMPBF

Overview

The LTC2633HTS8-HI10#TRMPBF is a dual-channel, 10-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 4.5V to 5.5V supply. The device utilizes a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C temperature range. The part incorporates a power-on reset circuit configured to initialize outputs to mid-scale in internal reference mode.

Feature Summary

• Dual 10-bit DACs with integrated 4.096V precision reference (±10ppm/°C drift)
• Maximum INL error of ±1 LSB and guaranteed monotonic operation
• Rail-to-rail output buffers with low noise (750µVP-P, 0.1Hz to 200kHz)
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the HI designation corresponds to the 4.096V full-scale voltage and internal reference mid-scale power-on reset behavior as defined in the manufacturer's selection guide. Ensure compatibility with the required 4.5V to 5.5V supply voltage range for specified performance.

Selection Notes

Select this component when a dual-channel DAC with high accuracy (±1 LSB INL) and a 4.096V output span is required. The HI suffix specifies the 4.096V full-scale voltage and mid-scale power-on reset state. For applications requiring lower supply voltages (2.7V–5.5V), the L-grade variant with 2.5V full-scale output should be considered instead. Verify that the I²C address configuration via the CA0 pin meets system addressing requirements.

Part Context

This part belongs to the LTC2633 family of dual I²C DACs available in 8-, 10-, and 12-bit resolutions. The HTS8 package denotes the automotive temperature grade (-40°C to 125°C) in an 8-lead TSOT-23 form factor. The HI code specifically defines the 4.096V full-scale voltage capability and the mid-scale power-on reset behavior for internal reference configurations within this product line.
