LTC2664HUH-16#TRPBF

Overview

The LTC2664HUH-16#TRPBF is a quad-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices. It features SoftSpan technology allowing five independently programmable output ranges up to ±10V. The device includes an integrated precision reference with a maximum temperature coefficient of 10ppm/°C and built-in rail-to-rail output buffers capable of driving ±10mA. It operates on analog supplies ranging from ±4.5V to ±15.75V and a digital supply from 1.71V to VCC+0.3V. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±4 LSB at 16 bits and a settling time of 20µs for a ±20V step. The component utilizes a 3-wire SPI/Microwire-compatible serial interface.

Feature Summary

• Quad-channel 16-bit resolution with independently programmable SoftSpan output ranges: 0V to 5V, 0V to 10V, ±2.5V, ±5V, and ±10V
• Integrated precision reference with 10ppm/°C maximum temperature coefficient and external reference capability
• Rail-to-rail output buffers guaranteeing monotonicity and driving ±10mA load current
• A/B toggle capability via dedicated pin or software command for dual-register operation

Applications

• Optical networking systems
• Precision instrumentation
• Data acquisition systems
• Automatic test equipment
• Process control and industrial automation

Procurement Notes

Verify the #TRPBF suffix indicates a tape and reel packaging configuration containing 2500 pieces. Confirm the H grade designation corresponds to the automotive temperature range of –40°C to +125°C. Ensure the specific lot date code meets project requirements as manufacturing processes may undergo changes documented in Product Change Notices.

Selection Notes

Select this part when four independent 16-bit channels are required within a single package. The H grade is necessary for applications operating between –40°C and +125°C. Verify that the system power supplies accommodate the specified voltage ranges and that the 32-lead QFN package footprint matches the PCB layout constraints.

Part Context

This component belongs to the LTC2664 family, which also includes 12-bit variants and commercial/industrial temperature grades. The HUH package denotes the 32-lead (5mm × 5mm) plastic QFN form factor. The TRPBF suffix specifically identifies the tape and reel shipping method for automated assembly.

Replacement Considerations

Direct replacements within the same family include LTC2664IUH-16#TRPBF for industrial temperature range (-40°C to 85°C) and LTC2664CUH-16#TRPBF for commercial range (0°C to 70°C). Other packages such as LFCSP are available under different part numbers but require schematic and layout verification.
