LTC2632HTS8-HZ8

Overview

The LTC2632HTS8-HZ8 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 supporting clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) error of ±2.5LSB, rail-to-rail output buffers, and guaranteed monotonicity across the -40°C to +125°C automotive temperature range.

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 ±2.5LSB max INL

Applications

Mobile Communications
Process Control and Industrial Automation
Automatic Test Equipment
Portable Equipment
Automotive Systems

Procurement Notes

Verify the specific ordering suffix #TRMPBF or #PBF against the required packaging format (tape and reel vs. tube). Confirm that the H-grade supply voltage requirement (4.5V to 5.5V) aligns with the system design, as this variant differs from the L-grade which supports lower voltages. Ensure the zero-scale power-on reset behavior meets system initialization requirements.

Selection Notes

Select this part when a dual-channel DAC with high accuracy and automotive reliability is required. The H-series designation indicates a 4.096V full-scale output necessitating a minimum 4.5V supply. The Z-suffix ensures outputs initialize to zero upon power-up, preventing transient errors in downstream circuits. Compare against the I-suffix if mid-scale initialization is preferred instead.

Part Context

This component belongs to the LTC2632 family of dual SPI DACs. The HTS8 identifier specifies the Automotive temperature grade (H), the 8-lead TSOT-23 package (TS8), and the 12-bit resolution (implied by the base model context for this specific suffix combination in the selection guide). It is distinct from the C-grade commercial version and the L-grade low-voltage version.
