National Semi invented the LM358 so I look at their datasheet.Originally Posted by Lesh
ST Micro says that its GBP is 1.1MHz when it has a 5V supply, but its graph shows 1.1MHz with a 30V supply and only about 500KHz with a 10V to 15V supply. ST Micro frequently get things mixed up.
TI says its GBP is only 700kHz typical when it has a 30V supply. No graphs.

i too want an receiver circuit for amplifying 40khz signal from GL402R receiver... i want amplified signal of max 5v what should be the gain and can i use LM358 for that...plz anyone provide me the circuit for that
At 40kHz an LM358 has a max output level of only 3V p-p and a max gain of only 25 if the supply is between 10V and 15V. If the supply is 5V then it can hardly amplify 40kHz.
An MC34071 single opamp, MC34072 dual opamp or MC34074 quad opamp) also have a minimum supply voltage of 3V and have inputs that work at ground in a single supply circuit but have full output level up to 100kHz and have a max gain at 40kHz of 200.
