LTC2633HTS8-HZ10#TRMPBF

Overview

The LTC2633HTS8-HZ10#TRMPBF is a dual 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 includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates a power-on reset circuit that clears outputs to zero-scale upon initialization.

Feature Summary

• Dual 10-bit DACs with integrated 4.096V precision reference (±10ppm/°C drift)
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• I²C interface with selectable standard (100kHz) or fast (400kHz) clock rates
• Power-on reset to zero-scale for consistent system initialization

Applications

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

Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the HTS8 package type matches the required 8-lead TSOT-23 footprint for the target PCB design.

Selection Notes

Select this part when a 4.096V full-scale output is required with a minimum supply voltage of 4.5V. The HZ code specifies a zero-scale power-on reset state, which is critical for applications where downstream circuits must remain inactive during startup. Verify that the I²C address configuration via the CA0 pin aligns with the system bus topology.

Part Context

This component belongs to the LTC2633 family of dual DACs, which offers various resolution options (8-, 10-, and 12-bit) and power-on reset configurations. The specific HTS8-HZ10 variant combines 10-bit resolution with the high-voltage internal reference option and zero-scale reset behavior, distinguishing it from mid-scale reset or external reference variants within the same series.
