Part Number: LM4675 Hello, How do you calculate the power consumption or the IC ? I only see a bunch of power information, or quiescent current in the datasheets. Thanks !
Part Number: LM4675 Hello there,
I am planing to use this amplifier for 1W @8ohm speaker and CR2032, 3V coin cell supply.
How much current it will draw?
Regards

Part Number: LM4675 Dear, Sir.
My customer is plaaning to realize the speakker cable disconnection datect function
during shutdown. They are looking for the higher output impedance product for
easy deteaction.
Accoding the datasheet of LM4675, the…
Part Number: LM4675 Hello,
I'm doing some emergency triage work on a a LM4675 design that is not passing EMI. It's used in a single-ended input:
IN+: has 51k ohm resistor + 0.1uF cap all in series to GND.
IN- has a 12.4k ohm resistor + 100uf…
Part Number: LM4675 We have a LM4675 design that we had TI review. So far we can't get any audio out of it. I tied it's shutdown pin to VDD and hooked up a signal generator at the speaker_mono signal. I'm putting in a 1Vpp 1kHz sine wave. …
Part Number: LM4675 Hi everyone,
we believe to have found an "anomalous" behavior of the device during its start-up transient (better to say exit from shutdown). We think that in this situation, which is quite long, roughly a few ms, there is…
Part Number: LM4675
Design with 5.65V(Max) to 4.75V(Min) input to Codex and AMP circuit; divisor circuit from 5V to shutdown pin using R1@47K, R2@22K, R2 to ground and shutdown. .01pf CAP added between R1 and R2
Problem is that originally when removing…
Part Number: LM4675 Hello,
I have been tasked to locate the BOM and schematic for the LM4675TLBD. The only documentation showing for this is the data sheet for the LM4675. Is this information going to be available?
Thank you!
Part Number: LM4675 Other Parts Discussed in Thread: TPA2011D1 , TPA2039D1 , Hi TI,
I would like to get some expert feedback regarding recent failures of amplifier chip L4675 on our customer’s boards. There was no audio output and
replacing the amplifier…
