LMP7300 Micropower Precision Comparator and Precision Reference with Adjustable Hysteresis
General Description
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 micropower (35 µW), low offset voltage (0.75 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 maintain a precise threshold voltage during level detection. The combination of low offset voltage, external hysteresis
