Redgarden is pleased to announce the availability of its trans-impedance amplifier (TIA) demonstration board (possibly the world’s first such board)! This TIA board can be used to convert the current from a photodiode to a voltage output with filtering and gain. The board has four separate channels (for four separate photodiodes) that can be assembled as needed for a variety of gains, bandwidths, and circuit topologies. The board is designed for very low-noise operation.

Unless otherwise agreed with Redgarden, the board is sold without components assembled. This lowers the price of the board and allows the user to more easily customize it for their application. For example, the desired gain of a TIA may vary from < 1kΩ to > 20MΩ! However, schematics and a bill of materials are provided with the board (for nominal component values in electronic form). All of the board components can be hand-soldered by someone with reasonable soldering skills (although some care and magnification may be needed).

The board can be purchased for $250 plus shipping (and tax in Colorado). Please email Kurt@RedgardenEngineering.com with your shipping address, and he will send you an invoice through PayPal.
