LTC2688: 16-Channel, 16-Bit Precision DAC
LTC2688 is a 16-channel, 16-bit, ±15 V, small form factor digital-to-analog converter (DAC) with an integrated precision reference converter.
This product is ideal for automatic test equipment, DAC-per-pin programmers, data acquisition systems, and closed-loop servo-control.
Key Features and Benefits
• A/B toggle with sinusoidal dither targets the specific requirements of Mach-Zehnder modulator (MZM) technologies and biasing topologies
• Highly compact 16-channel Software programmable bipolar voltage DAC improves overall system flexibility
• Monitor mux that allows the user to sense DAC voltages and DAC output currents to reduce calibration time and system complexity
Applications
• Communications: 5G, optical wired communications
• Instrumentation and Measurement
• Industrial Automation
• General-Purpose
Evaluation Board
The LTC2688 can be evaluated with the DC2873A-B and DC2026C.
