Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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.
