Product datasheets

The following documents provide in-depth technical description of the operation of Intan Technologies integrated circuits and evaluation boards.

• RHA2000 Series amplifier chip datasheet
• RHA2000-EVAL evaluation board datasheet
• FAQ: Why is the gain of the RHA2000 Series ampifiers fixed at 200?

Evaluation board software

The following Windows-based software is for use with the RHA2000-EVAL board which allows users to quickly evaluate the functions and performance of the Intan Technologies RHA2000 Series amplifier chips.

• Intan USB evaluation board software, v1.03 for Windows (last updated May 24, 2011).
  Note: This software can be run without an evaluation board; it will generate synthetic neural data for demonstration purposes if no evaluation board is connected.
• Windows USB D2XX driver required for evaluation board, and installation guide.
• MATLAB m-file for reading saved data files from evaluation board software.
• Python script for reading saved data files from evaluation board software.

Printed circuit board design resources

We offer printed circuit board (PCB) design resources in Eagle PCB format. (Eagle PCB is available in a freeware version for trial use.) For users of other PCB software, we show recommended PCB part footprints in the RHA2000 Series datasheet.

• Complete design files for RHA2116 amplifier board (type 1): schematic file, board file, parts libraries, complete bill of materials, graphical assembly guide, sample Gerber output files.
• Intan Technologies parts library in Eagle PCB format. This library includes all chips in the RHA2000 series of amplifier arrays.
