LTC2633HTS8-HZ10#TRPBF

Overview

The LTC2633HTS8-HZ10#TRPBF is a dual 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. 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 communicates via 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. Upon power-up, the outputs reset to zero-scale.

Feature Summary

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

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm that the H-grade designation matches the required automotive temperature range of –40°C to 125°C. Ensure the supply voltage in the target application remains within the 4.5V to 5.5V window specified for the H-series devices to maintain electrical performance guarantees.

Selection Notes

Select this part when a dual-channel DAC with high accuracy (±1 LSB INL) and a fixed 4.096V full-scale range is required. The HZ10 variant is appropriate for designs needing zero-scale power-on reset behavior. For applications requiring lower supply voltages (2.7V–5.5V), the L-series variants must be considered instead. Verify that the I²C bus speed requirements align with the standard or fast mode capabilities.

Part Context

This component belongs to the LTC2633 family of dual DACs, which also includes 8-bit and 12-bit resolution options. The 'H' suffix denotes the higher voltage/full-scale variant (4.096V), while 'Z' specifies the zero-scale power-on reset configuration. The 'TS8' indicates the 8-lead ThinSOT package type. Other family members like the LTC2635 offer quad channels in different packages.
