Suited for PLC (programmable logic controller) analog outputs, the MAX15500/MAX15501 industrial signal conditioners feature a programmable voltage-output amplifier and a current-output amplifier, ±10 V and 4 to 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 give a 5% and 20% overrange, providing a programmable current up to ±24 mA or voltage up to ±12 V proportional to a control-voltage signal, as required by PLC manufacturers.
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. Housed in a 32-pin TQFN package, the chips features 2-ppm/°C gain-error drift over temperature, 40-µs settling time, and –40° to 105°C industrial temperature range.
