Part Number: PGA2311 Other Parts Discussed in Thread: TPS7A49 Hello, I'm designing a high end quality A class amp and would like to use PGA2311 to add digital volume control. My design has separate analog ground for both channel in order to keep a very…
Part Number: PGA2311 Hi Team,
PGA2311 has zero-crossing detection function for noise-free level transitions. Does it mean that PGA2311 automatically changes between the specific gain setting with lowest output noise when there is no input signal and the…
Part Number: PGA2311 Hi to all!
I am studying datasheet of PGA2311 Stereo Volume Controller and in Chapter 10 (Figure 15) there is recommended PCB layout. I've noticed digital and analog ground are tied together in single point. Now, place jumper between…
Part Number: PGA2311 Other Parts Discussed in Thread: TPA3245 Hi,
My customer would like to design an amplifier system with a MSP430 MCU, PGA2311 and a TPA3245 Class D amp.
Is there any MSP430 sample code to interface with the PGA2311 through the serial…
Hi Pascal,
I apologize for the delay in replying. I've been out of office for the last week. We have a few tests to suggest:
First, after the PGA2311 becomes "stuck", could you try heating it with a heat gun, and seeing if the device recovers?…
Hi Ian,
Thanks for the information.
I just brought ICL7660, it also works as voltage inverter. but I have another problem.
I have connected the PGA2311 by the typical application in figure 13 from the datasheet ( www.ti.com/.../sbos218d.pdf)
While streaming…
Part Number: PGA2311 Hello,
I'm using a PGA2311. I have a +5vdc rail feeding a microcontroller and the digital side of the PGA; an isolated DC-DC converter (CUI PQMC1-D5-D5-S) creates the rails for the audio portion. I am having trouble with the…
Part Number: PCM5102A Other Parts Discussed in Thread: PGA2311 , PCM5102 , Hallo,
in my current design I connect the analog Audio Outputs from the PCM5102 DA Converter (using the suggested Output filter 470R+2,2nF) to the Input of a PGA2311 adjustable Gain…
