OUT1:
Push-pull output.
The absolute maximum rating for the output
source current is −50 mA.
The output source current is set by the external
resistor connected to the RB1 pin.
OUT2:
Push-pull output.
The absolute maximum rating for the output
source current is −50 mA.
The output source current is set by the external
resistor connected to the RB2 pin.
GND:
Ground
OUT3:
Open-collector output.
The absolute maximum rating for the output
current is +50 mA.
V
Power supply.
Provide the operating supply voltage in the range
1.8 V to 14 V.
OSC:
Connection for the capacitor and resistor that
determine the oscillator frequency. Use a capaci-
tor in the range 100 pF to 1 000 pF and a resistor
in the range 3 kΩ to 33 kΩ. Use an oscillator
frequency in the range 20 kHz to 1 MHz.
IN+3:
Noninverting input to the error amplifier 3.
IN−3:
Inverting input to the error amplifier 3.
FB3:
Output from the error amplifier 3.
This circuit can provide a source current of −31
µA or a sink current of 0.5 mA (minimum).
