Low Input Bias Current Op Amps (≤100 pA)
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

Transducers For Photodiodes
Photodiodes convert incoming electromagnetic radiation into electrical charge carriers. If photodiodes are short circuited an electrical current (photocurrent) proportional to the incident radiation intensity (number of photons per second) is induced. These photocurrents are generally small and cover the range from femtoampere (fA) to microampere (µA). Signal transducers transform this weak photocurrent to robust standard signals for reliable data transmission and simple data acquisition.

16-element Si photodiode array
S12362-321
The S12362/S12363 series is a back-illuminated type 16-element photodiode array specifi cally designed for non-destructive X-ray inspection. These are modified versions of our previous products (S11212 series: 1.575 mm pitch). The pitch has been changed to 2.5 mm. The back-illuminated photodiode array is also simple to handle and easily couples to scintillators without having to worry about wire damage because there are no bonding wires and photosensitive areas on the back side.
