The AD202KN is a Miniature Isolation Amplifier with maximum nonlinearity of ±0.025% for the AD202K (±0.05% for the AD202J) and low drift over-temperature. General purpose two-port transformer-coupled Isolation Amplifier that may be used in a broad range of applications where input signals must be measured, processed and/or transmitted without a galvanic connection. These industry standard isolation amplifiers offer a complete isolation function, with both signal and power isolation. The AD202 provide total galvanic isolation between the input and output stages of the isolation amplifier through the use of internal transformer-coupling.
