Synopsis for Investor:

  * The MAX15500/MAX15501 output signal conditioners are ideal for
    PLC (programmable logic controller) analog outputs, distributed
    I/O, embedded systems, and industrial control and automation.
  * These devices provide better accuracy, more integration, greater
    design and daisy-chain flexibility, and a smaller total solution
    than the competition.
  * These products have extensive error-handling and the best error-
    reporting capabilities in their class of products.
  * The MAX15500/MAX15501 are the first complete output signal
    conditioners to operate directly off of a 24V field supply and
    the first to survive +/-35V. This voltage protection saves money
    and board space as additional protection circuitry, typically
    required in other solutions, is not necessary.

These devices offer the industrial market a unique combination of higher functionality, greater integration, and smaller total solution size than competitive devices. They feature unprecedented integration: a programmable voltage-output amplifier and a current-output amplifier; +/-10V and 4-20mA outputs operating directly from a 24V field supply; +/-35V circuit protection; extensive error reporting capability; and daisy-chain flexibility.

The MAX15500/MAX15501 save board space and design time in 4-20mA and/or bipolar/unipolar voltage-output applications. They are ideal for PLC (programmable logic controller) analog outputs, distributed I/O, embedded systems, and industrial control and automation. Their high integration adds flexibility for designs. Use a single device for channel-isolated applications or multiple devices for group-isolated applications.

Optimized for PLC Modules

The MAX15500/MAX15501 simplify the design of PLC modules. Typical competitive signal conditioners need precision-matched resistors to track voltages well over temperature. The MAX15500/MAX15501s' integrated voltage amplifier and voltage-to-current converter eliminate the need for those additional resistors, thus saving valuable board space. Only the current gain-setting resistor is external to the device. They offer extensive fault detection, including open-circuit load in current mode, short-circuit load in voltage mode, overtemperature, and supply brownout. Both intermittent and permanent load faults can be detected. If a fault occurs, the open-drain fault-interrupt pin will be pulled low. These are the only devices on the market with all these integrated features.
