Frequently asked questions
Can MC1458DR replace LM358 in a circuit?
The MC1458DR and LM358 are both dual general-purpose op-amps with similar pinouts and supply ranges. The MC1458DR offers a 1 MHz GBW versus the LM358's typical 700 kHz, and its input bias current of 80 nA is higher than the LM358's 45 nA typical. Check the common-mode input range and output swing against your circuit — the MC1458DR's output can swing closer to the rails than the LM358's, but the input range is narrower. In many non-critical signal conditioning roles it is a drop-in swap, but verify the specific DC conditions.
Can MC1458DR be used as a comparator?
The MC1458DR is designed as a general-purpose op-amp, not a comparator. It lacks the open-collector output and fast propagation delay of a dedicated comparator. Using it as a comparator may cause saturation recovery delays and increased power dissipation. For comparator applications, consider a part like the TLV9362IDDFR which is specified for rail-to-rail output and faster response.
