Part Number: LM4838 Other Parts Discussed in Thread: LM4952 , Hi Team,
I am designing a circuit with the LM4952, and I have two questions. 1. About pop noise during shutdown operation If the shutdown operation is turned OFF → ON or ON → OFF when there is…
I could only find this voltage-controlled amplifier:
In addition, there are some audio amplifiers that have volume control through DC level, please see the suggested devices below:
The LM4951A could be an alternative for the LM4990, it supports higher power supply voltage (9V):
If you are looking for a 12V level, the LM4952, LM4950 or LM4752 could be other solutions.
The majority of the new devices have digital control as there is usually a SoC in every system.
We have several DC volume controlled devices, however output power might be short for your spec, a couple options are below:
We are see the Old LDO have similar issue, need high ESR CERAMIC or TANTALUM.
Does LM4838 oscillation is similar issue?
Audio amp LM4952/LM4950/LM4940
