LTC2666HUH-12#TRPBF

Overview

The LTC2666HUH-12#TRPBF is an octal, 12-bit digital-to-analog converter (DAC) featuring SoftSpan technology for independently programmable output ranges. It integrates a precision 2.5V reference with a maximum temperature coefficient of 10ppm/°C and rail-to-rail buffered outputs capable of driving ±10mA. The device supports five output spans: 0V to 5V, 0V to 10V, ±2.5V, ±5V, and ±10V. It operates on analog supplies from ±4.5V to ±15.75V and includes an 8:1 analog multiplexer, A/B toggle capability, and a 3-wire SPI/Microwire interface compatible with logic levels as low as 1.71V.

Feature Summary

Octal 12-Bit Resolution with Independently Programmable SoftSpan Output Ranges
Integrated Precision Reference with 10ppm/°C Maximum Temperature Coefficient
Rail-to-Rail Buffered Outputs Driving ±10mA Guaranteed Load Current
Built-in 8:1 Analog Multiplexer and A/B Toggle Capability

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 format 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 prior to ordering.

Selection Notes

Select this model for applications requiring eight independent channels with distinct voltage ranges. The H-grade variant is necessary for environments exceeding 85°C. Verify that the IOVCC supply voltage supports the required 1.71V minimum for high-speed serial clocking up to 50MHz.

Part Context

This component belongs to the LTC2666 family of SoftSpan DACs. The HUH package identifies the 32-lead, 5mm × 5mm QFN form factor. The suffix 12 specifies 12-bit resolution, while TRPBF denotes the tape and reel quantity and lead-free finish status.
