LTC2632HTS8-LZ8#TRMPBF

Digital To Analog Converters Overview

The LTC2632HTS8-LZ8#TRMPBF is a dual 8-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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with 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 over the specified temperature range.

Digital To Analog Converters Feature Summary

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration. Confirm that the HTS8 designation corresponds to the Automotive temperature grade (-40°C to 125°C) and TSOT-23 package type as defined in the manufacturer's selection guide. Ensure compatibility with system power supply requirements for the LTC2632-H series if applicable, though the LZ8 suffix typically aligns with the 2.7V-5.5V operating range.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel, low-pin-count DAC with an integrated reference is required for space-constrained designs. The 8-bit resolution offers a balance between cost and performance for applications not requiring high precision. The zero-scale power-on reset feature ensures safe initialization for downstream circuits sensitive to nonzero outputs during power-up. Verify that the 2.5V full-scale output range meets the input requirements of subsequent stages.

Digital To Analog Converters Part Context

This part belongs to the LTC2632 family of dual DACs, which includes variants with 10-bit and 12-bit resolutions, different full-scale voltages (2.5V or 4.096V), and various power-on reset behaviors. The 'H' grade denotes the automotive temperature range, while 'L' denotes commercial. The 'Z' suffix specifies the zero-scale reset option, distinguishing it from mid-scale reset variants like 'I' or 'X'.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other LTC2632 variants with different resolutions or reset configurations, such as LTC2632HTS8-LZ12#TRMPBF for higher resolution. Cross-family replacements may require evaluation of pin compatibility, interface protocols, and reference accuracy. No public confirmed substitute part numbers outside the LTC2632 family are provided in the source material.
