Description
Amplified Photodiodes for High Sensitivity Detection
The Amplified Photodiodes are engineered to provide a complete light detection and signal amplification solution in a single compact device. By integrating a silicon photodiode with a precision operational amplifier, these devices eliminate the need for external amplification circuitry, simplifying system design while improving signal reliability.
Designed for applications that demand accurate and stable light measurement, the Amplified Photodiodes deliver a high transimpedance gain of 10 MΩ. This ensures that even low levels of incident light are converted into strong, usable electrical signals. With a bandwidth of up to 10 kHz, the devices are well suited for applications that require consistent response without compromising signal clarity.
The Amplified Photodiodes support both single and dual rail power supplies, offering flexibility for different system architectures. In single supply operation such as 5V systems, the devices produce a positive going pulse, making them easy to interface with standard electronics and digital systems.
These photodiodes are available in multiple configurations, including flat window, lensed window, and eye response options. This allows engineers to select the most suitable design for their specific application, whether it involves infrared detection, enhanced light collection, or human eye response matching.
With low noise characteristics and stable performance across a wide operating temperature range, the Amplified Photodiodes are ideal for demanding environments. Their compact TO5 package ensures easy integration into space-constrained designs, making them a practical choice for industrial, defense, and scientific applications.
