Analog Devices / Maxim Integrated MAX15500 Analog Output Conditioners
Analog Devices Inc. MAX15500 Analog Output Conditioners provide a programmable current of up to ±24mA or a voltage of up to ±12V proportional to a control voltage signal. The control voltage is typically supplied by an external DAC with an output voltage range of 0 to 4.096V for the MAX15500. The output current and voltage are selectable as either unipolar or bipolar. In the unipolar configuration, a 5% Full-Scale (FS) control voltage produces a nominal output of 0A or 0V to achieve under-range capability. A control voltage of 100%FS produces one of two programmable levels (105%FS or 120%FS) to achieve over-range capability. The outputs of the MAX15500 are protected against overcurrent conditions and a short to ground or supply voltages up to ±35V. The devices also monitor for overtemperature and supply brownout conditions. The supply brownout threshold is programmable.Features
