New from Maxim are the MAX15500 and MAX15501 industrial analog-output signal conditioners. These devices offer the industrial market a combination of high functionality, great integration and small total solution size. They integrate a programmable voltage-output amplifier and a current-output amplifier; ±10 V and 4-20 mA outputs operating directly from a 24 V field supply; ±35 V circuit protection; extensive error reporting capability; and daisy-chain flexibility.
The devices are suitable for PLC (programmable logic controller) analog outputs, distributed I/O, embedded systems, and industrial control and automation. A single device can be used for channel-isolated applications or multiple devices for group-isolated applications.
Typical 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. 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, over-temperature 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. The status of the fault bits is available through the SPI interface.
The analog output conditioners give a +5% and +20% over-range, providing a programmable current up to ±24 mA or voltage up to ±12 V proportional to a control-voltage signal. The control voltage is typically supplied by an external DAC with an output voltage range of 0 to 4,096 V for the MAX15500, and 0 to 2,5 V for the MAX15501. The output current and voltage are selectable as either unipolar or bipolar. Additionally, a HART signal may be added to the input signal.
