AD208 High Precision, Low Offset, mV Input Isolation Amplifier

The AD208 is a high precision, two-port, transformer-coupled isolation amplifier expressly designed for applications that require the amplification and isolation of extremely low level (i.e., ±mV) signals. The innovative front-end circuit design of the AD208 ensures the low offset characteristics and stable high gain properties of the AD208. The AD208 is fully compatible with the SIP style packaging of Analog Devices' low cost AD204 family of isolation amplifiers.
