Part Number: TPA6138A2 Hello Professional, My customer has questions for TPA6138A2 regarding electric characteristics. Could you provide below characteristics? ・Input Impedance ・Input bias current ・Input offset voltage(Is it same as Output offset / 2[V/V]…
Part Number: TPA6138A2 Hello,
What voltage swing is this device rated to for 10kohm loads? It looks like its +1dBV at 32ohms.
We're looking to see if it can swing 2Vrms at 10kohm loads.
Thanks, Nick
Part Number: TPA6138A2 Hello,
I am looking for assistance in choosing appropriate passive component values for use with the TPA6138A2. I will be generating two 0-3.3V PWM signals via an MCU and wish to produce analog audio signals suitable for listening…
Part Number: TPA6138A2 Hi expert,
I am checking with TPA6138A2 datasheet and not able to find a thermal protection function.
If the device runs a continuous full power output, like 3.3VDD, 16ohm, 10%THD, is there any concern regarding the reliability…
Part Number: TPA6138A2 Other Parts Discussed in Thread: TPA6130A2 Dear Sirs,
My customer needs protection against output pins short to GND when Mono plug is connected.
I checked the data sheet and found the notation of Short-circuit protection. However…
TPA6138A2 / TPA6139A2 don't support 8ohms load
I shorted the inputs of LM4880 to GND before the input AC coupling caps and still pops
Also tried to connect the LM4880 directly to the DAC, bypassing the buffer (NE5532), still pops.
Any suggestions…
Part Number: TPA6138A2 Dear officer,
The datasheet of TPA6138A2 claims that 'Low THD+N < 0.01% at 10 mW Into 32 Ω'.
May I know under what test condition, what kind of source was used to drive this amplifier, or what test circuit was applied…
Part Number: TPA6138A2 Hi,
