AMIS-49250

AMIS-492x0 AMIS-492x0 Fieldbus MAU Overview AMIS−492x0 Fieldbus MAU (Media Access Unit) is a transceiver chip for low speed FOUNDATION® Fieldbus and Profibus PA devices. The AMIS−49200 was originally designed to be a near pin-for-pin replacement of the Yokogawa mSAA22Q MAU. “Near pin-for-pin” means that associated component values may change, but no board changes are required. A micro-leadframe package option (NQFP) is also available, the AMIS−49250. Features AMIS−492x0 Fieldbus MAU is a transceiver IC for low speed FOUNDATION Fieldbus and Profibus PA devices. It incorporates the following features: All Node Power can be Supplied by the Bus, via the AMIS-492x0 Current Consumption 500 mA (Typ) VCC Voltage: 6.2 V to 4.75 V VDD Voltage: 5.5 V to 2.7 V Compatible to IEC 1158−2 and ISA 50.02 Shunt Regulator Voltage Reference (Internal Only) Series Regulator Band-pass Filter Slew Rate Control Segment Current Control Low Voltage...
