LM1458 in a circuit

A gain-of-three channel beside a unity-gain follower.

LM1458N/NOPB on ±15 V rails. VIN 0.50 V connects to pins 3 and 5. Pin 1 feeds pin 2 through 20 kΩ; 10 kΩ joins pin 2 to 0 V. Pin 7 joins pin 6 directly. Both supply rails have 100 nF bypass to 0 V.
All VIN labels share one signal. All ground symbols are the 0 V supply midpoint.

Connect it, step by step

Follow the component values and pin connections

Connect power

Use +15 V at pin 8 and −15 V at pin 4, with a 100 nF bypass from each rail to signal ground.

Wire the feedback

Add the 20 kΩ / 10 kΩ network to channel A and join pins 7 and 6 for channel B.

Read both outputs

At a nominal input of 0.50 V, expect about 1.50 V from A and 0.50 V from B under light DC loading.
