Digilent USB-3114 Voltage and Current Output USB Devices

Features and Specifications

• 16 high-drive voltage output channels
• 16-bit resolution
• Voltage output +/-10 V, 0 V to 10 V
• 100 S/s update rate
• Eight digital I/O
• One counter input

The USB-3114 is a data acquisition device that provides 16 channels of high-drive analog voltage output, high output current, eight digital I/O connections, and one 32-bit event counter. Each voltage output of the USB-3114 has a high-drive current output capability, allowing each voltage output to sink/source up to 40 mA of load current.

The USB-3114 has four quad (4-channel) 16-bit digital-to-analog converters (DAC). You can set the voltage output range of each DAC channel independently with software for either bipolar or unipolar. The bipolar range is +/-10 V, and the unipolar range is 0 to 10 V. The outputs may be updated individually or simultaneously.

The USB-3114 features eight bidirectional digital I/O connections. You can configure the DIO lines as input or output in one 8-bit port. All digital pins are floating by default. A screw terminal connection is provided for pull-up (+5 V) or pull-down (0 volts) configuration.

The 32-bit counter can count TTL pulses. A bidirectional synchronization connection allows you to simultaneously update the DAC outputs on multiple devices.

The USB-3114 is powered by a 5 volt, 2 amp AC power adapter that is shipped with the board. All I/O connections are made to the screw terminals located along each side of the USB-3114.

USB-3100 Series Overview

The USB-3100 Series features up to 16 analog outputs, 8 digital I/O, and one 32-bit counter input. Each channel is software-selectable for either a bipolar voltage output range of +/-10 V or a unipolar range of 0 V to 10 V. Channel outputs can be updated individually or simultaneously. USB-3102 also features 0 mA to 20 mA of current output. Each DAC controls a voltage/current channel pair simultaneously. Each channel pair can be updated individually or simultaneously.

• USB-3102 - 4 Channels
• USB-3104 - 8 Channels
• USB-3114 - 16 Channels

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, MATLAB, Linux, and Python.
