- 40-pin QFN compact package with SPI serial interface enabling space-efficient multi-channel DAC integration on dense PCBs
What is LTC2668HUJ-16#PBF used for?
The LTC2668HUJ-16#PBF is designed for industrial process control systems and automated test equipment where 16 independent precision voltage outputs spanning -10 V to 10 V must be controlled from a single device. Its 16-bit resolution and integrated 10 ppm/°C reference minimize calibration overhead in multi-axis motor controllers, programmable power supplies, and signal generation boards. It is also well-suited for medical device calibration platforms and aerospace avionics test systems requiring traceable and stable analog output across temperature.

Frequently Asked Questions
How does the integrated 10 ppm/°C reference in LTC2668HUJ-16#PBF reduce system-level design complexity?
By integrating a precision voltage reference with a maximum drift of 10 ppm/°C, the LTC2668HUJ-16#PBF eliminates the need for an external reference IC, saving board space and reducing BOM cost. Over a 50°C temperature range, output error from reference drift is limited to just 500 ppm, which translates to less than 5 mV of error on a 10 V full-scale output, meeting the requirements of most precision industrial control applications.
What makes LTC2668HUJ-16#PBF suitable for automated test equipment requiring 16 independent analog outputs?
Automated test equipment benefits from the LTC2668HUJ-16#PBF's 16 independently controllable 16-bit DAC channels that each cover a ±10 V output range via SoftSpan programming. This means a single IC can simultaneously stimulate 16 analog inputs on a device under test with resolutions of approximately 305 µV per LSB, reducing the number of ICs in the test system and the associated routing complexity.
For a multi-axis industrial servo controller, how does the serial SPI interface of LTC2668HUJ-16#PBF simplify connection to a microcontroller?
The LTC2668HUJ-16#PBF uses a standard 4-wire SPI serial interface with binary input coding, requiring only MOSI, SCK, and CS lines from the host microcontroller to program all 16 DAC channels. This is far fewer connections than a parallel-bus DAC equivalent, allowing a compact 40-pin QFN device to control 16 servo drive analog command signals from a single SPI port on processors like STM32 or DSP-based motor controllers.
