TLC272 Replacement in variable power supply

[anoop401]

Hi all,
In the circuit diagram shown, they have used TLC272. Can I replace it with any other OP-AMP, like TL082,72 etc ?? Similarly, what part can replace BAT85 ? Any general Schottky diode ?
Thanks for the reply.
Anoop.

Hi,

If you just want that the circuit works somehow, then you can use almost any other Opamp.
But if you want the same performance, then it might be difficult.

In some cases (with slow Opams) the circuit may oscillate. This may lead to self distruction and it may destroy the speakers.

Replacing BAT85 isnot that critical. Just look for a schottky diode with about the same parameters. Take care of forward voltage.

Any OPAMP with input voltage range including negative rail and suitable output voltage range, TL072 e.g. won't work. Look for "single supply" or "rail-to-rail" OPs in a first order.

If you have little OP choice available, you may try LM358/LM324.

TLC272 is a general purpose single power supply dual operational amplifier. It have an advantages of low noise output. TL082 is audio grade op amp but it is dual power supply, TL072 not suite slew rate/speed is low and also dual power supply
OPA2725 will give better performance than TLC272 check the availability (Or any op amp with high slew rate and low noise with single power supply is suitable)

BAT85 is a general high speed schottky diode 30V,200mA,
NTE585 is 40V,1A schottky diode
