MAX15501GTJ+

The MAX15501GTJ+ is an industrial analogue current/ voltage-output conditioner in 32 pin TQFN package. The analogue output conditioner provides a programmable current up to ±24mA or a voltage 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 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 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 MAX15501 is protected against overcurrent conditions and a short to ground or supply voltages up to ±35V. The supply brownout threshold is programmable. The MAX15501 is a programmed through an SPIK interface capable of daisy-chained operation.
