Hello Uriel,
1. Using 4x PGA4311 would be the most efficient and best-performing solution for 16 channel volume control.
2. No special microcontroller is required. The only requirement is that a 3-wire serial communication interface (SPI) is available…
Other Parts Discussed in Thread: PGA4311 , OPA1622 , TINA-TI Hi,
I used OPA1622 for LPF, follow PGA4311,a part of schematic as below(4pcs OPA1622 role as OR+/-, OL+/-). The problem is: If OPA1622 is Enabled, when a cellphone approaching, there is beep…
Other Parts Discussed in Thread: PGA4311 , LM1972 , PGA2311 Hello,
I'm building a "digitally controlled analog mixer" with some mic inputs and stereo linear inputs. I need each channel to have a volume slider.
We considered the PGA4311, but a) it…
Other Parts Discussed in Thread: PGA2505 , PGA4311 I have designed a microphone amplifier circuit with PGA2505. It works OK, but every time I change PGA2505's GAIN, I would hear "clicks" or "pops". The DC Servo and Zero crossing detect of PGA2505 are…
Other Parts Discussed in Thread: PGA4311 , PCM1681 hello I'm making a project with PCM1681 and cascade the PGA4311. DAC output, you have to put a low pass filter. At the exit of PGA4311 I put an opamp. Now, to simplify the circuit, I can put the low pass…
Hello Maruthi,
The PGA4311 is a low-power device which is only used to drive line-level audio signals into relatively high-impedance loads. Its thermal resistance and maximum power dissipation should not be a concern, since it will be a very small contributor…
Hi, after mi last mesage We finish other proyect and I will satrt to work with the pga4311 to made a gain control of our desing.
After reading the data shhet I have some easy questions, to conect at the output of each chanels of the atenuator, Iread…
Hi Tony,
Welcome to E2E, Thanks for your interest in our products!
This is an unexpected behavior, did you find any issues or strange behavior on the device before the channel dies?
As an alternative I would recommend you to take a look to the…
Hi Jevgenij,
Welcome to e2e.
You can take a look at PGA2320, PGA2310, PGA4311 and PGA2311 although these are volume control devices.
If you need further control on the signal you could try with some of our codecs from the TLV320AIC family devices…
