The product serves as a low-noise preamplifier circuits for measurement and calibration of implantable electronic chips cochlea. Due to the location directly on the chip of the cochlea can process signals of extremely low levels, which would be due to the surrounding interference otherwise undetectable. It is adapted to a differential measurement to four sensing elements of the sensor (2 measuring and reference 2) to maximize the useful signal components.
