PRINCIPLE FUNCTION

Amplification and conversion of differential input voltages or

those referenced to ground to industrial standard current (0/4...20mA) or

voltage signals (e.g. 0...5/10V, 0.5...4.5V)

TYPICAL APPLICATIONS

• Transducer for sensor applications

• Analog industrial output stage for microprocessor applications

• Modular signal conditioning with digital correction (Frame ASIC [1])

• Protected output stage power network

• Impedance converter
