Other Parts Discussed in Thread: PGA2320 , PGA2311 Hi, I'm designing a power amplifier which uses PGA2320/2311 as input attenuator. This device is controlled by a USB SPI bridge, and here is the question. What is the relationship between VA and VD? Can…
Other Parts Discussed in Thread: PGA2320 , LME49600 , LME49720 I would like to have more output current (Short-Circuit Current) for my audio device. would it be possible to connect 2 or 3 PGA2320 in parallel? (meaning shorting pin1 of the first PGA2320 to…
Other Parts Discussed in Thread: PGA2500 , PGA2320 , PGA2310 Hi Experts,
Good day. I would like to ask your assistance in choosing pre-amp PGA needed for audio application.
Cx share the following spec's for this:
Input Signal Range: 106uV pk to (25V…
Other Parts Discussed in Thread: PGA2320 I have a problem with a PGA2320 application. It's a headphone amplifier.
I have permanently enabled ZCEN by tying it high with a 10k resistor. ZCEN is the zero-crossing detector which prevents volume changes…
Hello finalstage,
You are describing a scenario which is actively debated amongst the audio gurus. Either one is an acceptable solution for high fidelity. The end result hinges strongly on design implementation. Let me elaborate a little.
If you use…
Hi Paul,
Perhaps something like PGA2320 or PGA2310 could be useful, you can check our Volume Control ICs here: https://www.ti.com/audio-ic/amplifiers/volume-control-ics/products.html

Part Number: PCM1792A Other Parts Discussed in Thread: PGA2320 Hi,
I have a project to develop an audio DAC board with 4 PCM1792a and need to interface with SPI.
My question is if SPI work in daisy chain like PGA2320 for example or do we have to interface…
Part Number: DRV134 Other Parts Discussed in Thread: INA134 , LM337 , PGA2320 , OPA1641 , OPA172 , OPA1652 Hi there / i wander if i can use the DRV 134 after the INA 134 without a buffer between them. the INA134 receiver to convert balance signal into unbalance…
Part Number: PGA2310 Other Parts Discussed in Thread: PGA2320 I've been looking for a digipot to use in my amplifier for the volume control etc.
The issue I have though is I need the pot to be floating, which it doesn't appear is possible with this…
