LTC2632HTS8-HZ8#TRPBF

Overview

The LTC2632HTS8-HZ8#TRPBF is a dual 12-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 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. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±2.5LSB, a settling time of 4.9µs at 5V, and a supply current of 0.5mA at 5V with the internal reference active.

Feature Summary

• Dual 12-bit DACs with integrated 4.096V precision reference (10ppm/°C)
• Automotive temperature grade (-40°C to +125°C)
• Power-on reset to zero-scale in internal reference mode
• Rail-to-rail output buffers with guaranteed monotonicity

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to the tape and reel packaging configuration required for the production line. Confirm that the H-grade automotive temperature range and H-series 4.5V minimum supply voltage align with the target system's power architecture before finalizing procurement.

Selection Notes

Select this part when a dual-channel DAC with high accuracy and automotive reliability is required. The HZ suffix indicates a zero-scale power-on reset, which prevents output glitches during startup. Ensure the system supply voltage remains above 4.5V, as lower voltages will prevent proper operation of the H-series internal reference.

Part Context

This component belongs to the LTC2632 family, which offers various combinations of resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset behaviors. The HTS8 designation identifies the specific automotive temperature grade, TSOT-23 package, and 12-bit resolution variant within this broader product line.

Replacement Considerations

Direct substitutes within the same family include LTC2632HTS8-HI8#TRPBF (mid-scale reset) or LTC2632HTS8-LZ8#TRPBF (2.5V full-scale). Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
