Industrial Analog Current/ Voltage-Output Conditioners General Description The MAX15500/MAX15501 analog output conditioners provide a programmable current up to Q24mA, or a volt- age up to Q12V 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 and 0 to 2.5V for the MAX15501. The output current and voltage are selectable as either unipolar or bipolar. In the unipolar configuration, a control voltage of 5% full-scale (FS) produces a nominal output of 0A or 0V to achieve underrange capability. A control voltage of 100%FS produces one of two programmable levels (105%FS or 120%FS) to achieve overrange capability. The outputs of the MAX15500/MAX15501 are protected against overcurrent conditions and a short to ground or supply voltages up to Q35V. The devices also monitor for overtemperature and supply brownout conditions. The supply brownout threshold is programmable. The MAX15500/MAX15501 are programmed through an SPIK interface capable of daisy-chained operation. The MAX15500/MAX15501 provide extensive error reporting through the SPI interface and an additional open-drain interrupt output. The devices include an analog output to monitor load conditions. The MAX15500/MAX15501 operate over the -40NC to +105NC temperature range. The devices are available in a 32-pin, 5mm x 5mm TQFN package.
