LTC2686IUJ-16#TRPBF

Overview

The LTC2686IUJ-16#TRPBF is an 8-channel, 16-bit voltage output SoftSpan DAC from Analog Devices Inc. It features independently programmable output ranges of 0 V to 5 V, 0 V to 10 V, ±5 V, ±10 V, and ±15 V. The device includes a precision internal 4.096 V reference with a maximum temperature coefficient of ±10 ppm/°C. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±3 LSB and a settling time of 3.5 µs for a ±5 V step. It operates on analog supply voltages between 4.75 V and 5.25 V, with digital I/O levels supported down to 1.71 V.

Feature Summary

Eight independent channels with full 16-bit resolution across all five selectable output ranges.
Integrated precision 4.096 V reference with ±10 ppm/°C maximum temperature coefficient.
Built-in rail-to-rail output buffers capable of sourcing or sinking up to 55 mA.
Supports asynchronous toggle and sinusoidal dither operations via three multifunctional pins.

Applications

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

Procurement Notes

Verify the #TRPBF suffix indicates tape-and-reel packaging distinct from tube variants. Confirm the 'I' grade designation corresponds to the -40°C to +85°C operating range. Ensure compatibility with the 40-lead LFCSP footprint during procurement planning.

Selection Notes

Select this model for applications requiring eight channels with bipolar outputs up to ±15 V. The 16-bit resolution and ±3 LSB INL make it suitable for high-precision tasks. Consider external references if tighter accuracy than the internal ±10 ppm/°C specification is required.

Part Context

This component belongs to the LTC2686 family of SoftSpan DACs. It shares architectural similarities with the LTC2688 but differs in channel count and output type. The IUJ-16 variant specifically denotes the industrial temperature grade and 16-bit resolution within the 40-lead LFCSP package.
