LTC2688HUJ-12#TRPBF

Overview

The LTC2688HUJ-12#TRPBF is a 16-channel, 12-bit voltage output SoftSpan DAC from Analog Devices. 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 an internal precision 4.096 V reference with a maximum temperature coefficient of ±5 ppm/°C. DC performance specifications include a maximum integral nonlinearity (INL) error of ±0.75 LSB and a differential nonlinearity (DNL) of ±0.25 LSB. The analog supply voltage (VCC) operates between 4.75 V and 5.25 V, while the digital I/O supply (IOVCC) supports levels as low as 1.71 V.

Feature Summary

16 independent channels with individually programmable SoftSpan output ranges up to ±15 V
Integrated precision 4.096 V reference with ±5 ppm/°C temperature coefficient
Built-in rail-to-rail output buffers capable of sourcing or sinking ±20 mA
Analog multiplexer for monitoring output voltage, load current, and junction temperature

Applications

Optical networking
Instrumentation
Data acquisition
Automatic test equipment
Process control and industrial automation

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to tape and reel packaging rather than tube packaging. Confirm the H grade designation ensures operation within the extended temperature range of -40°C to +125°C. Ensure the specific revision level matches design requirements.

Selection Notes

Select this model for applications requiring high channel density with flexible bipolar and unipolar voltage outputs. The 12-bit resolution is suitable for general-purpose control loops. Consider the external reference mode if higher accuracy than the internal ±5 ppm/°C reference is required.

Part Context

This component belongs to the LTC2688 family of SoftSpan DACs. The HUJ package indicates a 40-lead LFCSP form factor. The -12 suffix specifies the 12-bit resolution variant, distinct from the 16-bit version. The TRPBF suffix denotes the specific packaging and lead-free compliance configuration.
