LM319 in a circuit

A physical fourteen-pin IC, divider and pulled-up collector.

LM319N at 5 V, 30 kΩ/20 kΩ divider to pins 5 and 10, VIN 1.5 V at pins 4 and 9, 10 kΩ pull-up on output 12, 100 nF bypass, output returns 3 and 8 grounded with supply 6.
Matching net labels are connected. Both channels have defined inputs; only output 1 is used.

Connect it, step by step

Follow the component values and pin connections

Power

Connect 11 to +5 V; connect 6, 3 and 8 to 0 V; bypass the analog supply.

Compare

Connect VIN to 4 and 9, and VREF to 5 and 10.

Read

Read output 12 through its 10 kΩ pull-up. Keep output 7 and all NC pins open.
