and conversion of differential input voltages (±400mV with a CMIR of 1.5 – VCC-3V) into an adjustable current output of 0/4...20mA, for example. The offset and maximum output currents are independently adjustable in a wide range. The IC is suitable for both 2- and 3-wire applications and as a HART® carrier IC. VCC = 6…35V Differential input ± 400mV AM452 IOUT = z.B.0/4...20mA VREF= 5/10V IS = max 10mA TYPICAL APPLICATIONS Transducers for differential input signals in current output values for: • Transducers for sensor applications with an internal sensing element supply • Drivers for the analog industrial power grid (e.g.
