Precision logarithmic and logarithmic ratio amplifier LOG100
Precision logarithmic and logarithmic ratio amplifier LOG100
LOG100 uses advanced integrated circuit technology to achieve its high accuracy, and it is easy to use with low cost and small size to make logical logarithmic arithmetic. The maximum error of amplifier in specifications ensure is more than 6 decimal input range (1nA ~ 1mA) and all possible I1 and I2 combinations. As to ensure the total error, it does not require the calculation of the concerned error. The circuit uses a special design which is compatible with film monolithic integrated circuit, including amplifiers, logarithmic transistors and low drift thin-film resistors. In order to guarantee maximum precision, the thin film resistor uses laser correction.
