Transimpedance Amplifiers (Gated)

SIMTRUM offers a wide range of transimpedance Amplifers which employs precision differential or single ended transimpedance input stages to provide for low offset and high linearity throughout the full dynamic range. The single ended input stage is required for applications where the current source is inherently grounded externally. These ranges of transimpedance amplifiers are particularly useful for the measurement of current from photodiodes. Use the table below to find a device that matches your needs. Accessories, software, and drivers are available - complete your purchase with a packaged solution that meets your needs.

The Gated Integrated Amplifier GIA 100 

Product Brochure: 

Gated Integrating AmplifierGIA100 Minimum Pulse Timing


employs dual monolithic switched integrators. When paired with a photodiode, the boxcar amplifier measures the energy of single optical pulses. The GIA100 design results in very low leakage error, charge injection error and pickup. The precision input stage may be configured for current or voltage inputs. It is also useful for signal processing in a wide range of applications such as photodiode monitoring and time domain signal analysis as the output is a voltage linearly proportional to the integral of the input during a period set by a TTL-compatible gate. The fast response time at high signal-noise-ratio makes the GIA series particularly useful in systems control feedback loops and online production control.
