ISOS 210AD Variable Gain Analog Signal Isolation Amplifier

   SunYuan ISOS 210AD series analog signal isolation amplifiers are magneto-electrically coupled hybrid integrated circuits in a low-cost, small footprint, standard single in-line SIP12 Pin flame retardant package. The module integrates multiple isolated DC/DC converter circuits and magneto-electrically coupled signal isolation converter circuits, which can complete the analog signal input/signal output/auxiliary power supply triple-isolated amplification and conversion by selecting a single power supply of 5V/12V/15V/24V, and supports single-ended and positive/negative bi-directional DC signal inputs and outputs. ISOS 210AD comprehensive functional design, the use of non-fixed gain method, the input signal through the input side of the preamplifier (gain of 1-100) amplified into the internal modulator for modulation, non-fixed gain input amplifier is convenient for the user according to the site working conditions of the flexible configuration of the use of the user can be achieved through the peripheral feedback gain resistors, etc., gain variable application, modulated signal through the transformer coupling transmission to the output side, demodulation circuit demodulated and amplified output. The triple-isolation design structure of the module allows the device to meet the signal input, signal output, auxiliary power supply is completely isolated, through the interruption of the ground loop and leakage path measures to inhibit common-mode voltage and noise to improve the accuracy and integrity of the measurement signal, is very suitable for single-channel or multi-channel analog signal isolation and amplification conversion applications. ISOS 210AD adopts the low-cost program of magnetic coupling, mainly used for EMC (electromagnetic interference) without special requirements of the occasion, the internal DC-DC isolated power supply in addition to the power supply to the internal amplification circuits, but also to the inputs and outputs of each outwardly provide a set of ± 15V / ± 5mA unregulated isolated power supply for two-wire sensor power distribution or to provide inputs preamplification, signal bias, Differential circuits, bridge circuits reference power supply. The products can meet the requirements of automotive grade field working environment with humidity, vibration and wide temperature range -40 ~ +125 ℃.
