Difference between TS5A22362, TS5A22364, and TS5A22366 [Dual SPDT analog switches for audio applications]

Other Parts Discussed in Thread: TS5A22362, TS5A22364, TS5A22366

Hello,

I'm looking for an audio switch. They have only found the Pericom PI3A288 to meet all their requirements, which are:


1. Works at 1.8V and 3.3V

2. Chip-scale package

3. Negative input

4. Inputs and outputs are isolated from each other when there is no power

TS5A22362 is the closest I can find, except it can't go down to 1.8V, and I'm not sure about requirement #4.

Do we have any devices that can meet the above requirements / can compete with PI3A288?

Thanks,

Jonathan Bender

    Jonathan,
    We do have parts that can compete with the PI3A228. You have found some competing parts looking at the TS5A22362, TS5A22364, and TS5A22366.

    The main difference between the three are:

    TS5A22362 audio signal switching

    TS5A22364 audio signal switching + click and pop reduction using a shunt resistor that is engaged on the non selected channel to dissipate any residual charge on the pin that could result in an audio click and pop when it is re-selected.

    TS5A22366 audio signal switching + can accept 1.8-V voltage level logic regardless of the supply voltage

    Thank you,
    Adam

    Hi Adam,

    Thanks for the quick/detailed reply!

    I've asked the customer your two questions (via the TSR). I don't know much about the end application, but either the TSR or I will come back with more info when we get it. I mentioned those three parts, so the customer may also have some direct feedback related to those options.

    Thanks,

    Jonathan
