LMP7300  
Micropower Precision Comparator and Precision  
Reference with Adjustable Hysteresis  
General Description  
Features  
The LMP7300 is a combination comparator and reference  
with ideal specifications for precision threshold detecting. The  
precision 2.048V reference comes with a 0.25% maximum  
error. The comparator features micopower (35 µW), low offset  
voltage (.75 mV max), and independent adjustable positive  
and negative hysteresis.

Hysteresis control for the comparator is accomplished  
through two external pins. The HYSTP pin sets the positive  
hysteresis and the HYSTN pin sets the negative hysteresis.  
The comparator design isolates the VIN source impedance  
and the programmable hysteresis components. This isolation  
prevents any undesirable interaction allowing the IC to main-  
tain a precise threshold voltage during level detection.

The combination of low offset voltage, external hysteresis  
control, and precision voltage reference provides an easy to  
use micropower precision threshold detector.  
Applications  
The LMP7300 open collector output makes it ideal for mixed  
voltage system designs. The output voltage upper rail is un-  
constrained by VCC and can be pulled above VCC to a maxi-  
mum of 12V. The LMP7300 is a member of the LMP®  
precision amplifier family.
