DESCRIPTION
1 AIN+
Non-inverting input of Op Amp. This is a PNP amplifier with the reference voltage as its supply voltage.
2 AIN–
Inverting input of Op Amp. This is a PNP amplifier with the reference voltage as its supply voltage.
3 AOUT
4 GND
Output of Op Amp. This is a NPN emitter follower output with a 22 kΩ internal on-chip pull-down resistor. Its supply
voltage is V_CC.
Ground.
5 COMPIN– Inverting input of Comparator. This is a PNP amplifier with V_CC as its positive supply voltage.
6 V_S
Reference voltage output. The output reference is typically 1.27 V. The output reference is derived from the series
combination of a NPN transistor (configured as a diode with the base shorted to the collector) and a 120 kΩ resistor.
7 COMPOUT Output of Comparator. It is an open collector output stage which requires an external pull-up resistor.
8 V_CC
Positive supply. Its operating range is 1.8 to 6.0 V.
