Analog Microelectronics AM400
AM400 is a monolithically integrated measuring amplifier with a parallel current and voltage output which has been specifically developed for the processing of differential input signals. It contains both an instrumentation amplifier input and an input for signals referenced to ground. The output ranges can be selected using external resistors, enabling AM400 to be configured for the analog 0/4...20mA and 0...5/10V industrial power network, for example.TYPICAL APPLICATIONS
