Industrial V/i Converter And Protector Ic - Analog Microelectronics

AM462 is a universal V/I converter and Amplifier IC with a number of additional functions. The IC basically consists of an Amplifier whose gain CAN be set externally, and an output stage which CAN convert voltage signals referenced to ground to industrial current signals. An additional reference voltage source for the supply of external components is also included in the device. A further Operational Amplifier CAN be connected up as a current source, Voltage Reference or Comparator One of the main features of the IC is its integrated protective circuitry. The device is protected against reverse polarity and has a built-in output current limit. Converter IC AM462 enables industrial current loop signals (e.g. of 0/420mA) to be produced relatively easily. Using the Frame ASIC concept [1] the IC CAN be connected up to a processor for signal correction. By AME, Inc.
