LTC2632CTS8-HZ8#TRPBF

Overview

The LTC2632CTS8-HZ8#TRPBF is a dual 8-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 a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. The part includes a power-on reset circuit that clears the outputs to zero-scale upon initialization. It is housed in an 8-lead TSOT-23 package.

Feature Summary

• Dual 8-bit DACs with integrated 4.096V reference
• Power-on reset to zero-scale for consistent startup
• 3-wire SPI/MICROWIRE interface supporting 50MHz clocks
• Rail-to-rail output buffers with guaranteed monotonicity

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the H-grade designation aligns with the required 4.5V to 5.5V supply range and automotive temperature specifications. Ensure the Z-power-on reset behavior matches system initialization requirements.

Selection Notes

Select this model if a 4.096V full-scale output is required with zero-scale power-on reset. The H-grade supports a wider operating temperature range compared to C-grade parts. Verify that the 8-bit resolution meets application accuracy needs, as higher resolution options like 12-bit are available in the same family.

Part Context

This component belongs to the LTC2632 family of dual DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (zero-scale or mid-scale). The HZ12 variant shares similar electrical characteristics but offers 12-bit resolution.
