JTIA1 Evaluation board with TIA for SiC and Si photodiodes available
Transimpedance amplifier with built-in voltage regulators for out SiC photodiodes or as all-purpose optical I/V converter

Our evaluation board JTIA1 with multi-stage amplification allows the measurement of photocurrents and their conversion to voltage output between 0 - 5 V. Built in voltage regulators accept a supply voltage between 4,5 V and 24 V. See the datasheet: JTIA1

General description :

The JTIA1 is a general purpose transimpedance amplifier board for photodiode measurements. The input side can either be directly equipped with TO5 or TO18 photdiodes via multi-header or via pin-header for external connections. A transimpedance amplifier provides photocurrent to voltage-output conversion (between 0 - 5 V) on the output side.

Gain Setting / Amplification:

The transimpedance gain can be set between three pre-configured values (10 / 100 / 1.000 MOhm) via jumpers. This corresponds to a photocurrent amplification between 0,1V/µA and 1V/nA. A second-stage amplifier allows for the additional, variable amplification in the range between 1x and 11x  via trim-pot. Custom values for feedback resistor and feedback capacitor can be manufactured or hand-soldered by the customer.

Power Supply:

The JTIA1 is internally regulated and supplied by a single-voltage supply between 6 V and 24 V and provides voltage output beween 0 V and 5 V. For operation with 5 V supplies, the internal voltage regulator can be set to 3,3 V. In this case, the input voltage can be as low as 4,5 V, with the drawback of a decreased output voltage between 0 V and 3,3 V. A negative supply-voltage is generated internally for minimum offset voltage.

New SiC Photodiodes with extended wavelength range
Our new JEA0,1X Photodiodes with "Extended SiC" show responsivity up to 400 nm

Our JEA-series of photodiodes will be joined by photodiodes with "Extended SiC", that allow detection up to around 400 nm.

While regular SiC does not show much responsivity above 360 nm, our "Extended SiC" from 6H-Siliconcarbide extends the wavelength response up to 400 nm.

At present the only manufacturer worldwide, ifw optronics offers inhouse-developed SiC photodiodes that offer the full UV spectrum up to 400 nm wavelength.

More Information about our JEA0,1X photodiodes are shown in the datasheet.
