Efficient design of CD4052B

Other Parts Discussed in Thread: CD4052B

Hi,

We want to know details about CD4052B to use it efficiently. (appropriate power supply, input and efficient output)

We found a data book of signal switch (scdd003a.pdf) in which details of CD40XX was described but CD4052B was not.

Where is a data book including the information of CD4052B?

regards

    I'm afraid there isn't an application report or data book on the CD4052B. When you say 'use it efficiently' -- what exactly do you mean? Are you trying to minimize power consumption? Channel resistance? Or are you just looking for the appropriate voltages that the part can handle?

    Hi Emrys,

    Thank you for your comment and I'm sorry my reply is late.

    We want to know appropriate voltages especially under conditions that :


    Xch_IN(Pin12) : 2.5Vrms (20KHz to 96KHz), Output Impedance = 10Ohm to a few KOhm @ Source signal
    Xch_OUT(Pin13): Output Load 1uF

    Ych_IN(Pin1) : 2.5Vrms (20KHz to 96KHz), Output Impedance = 10Ohm to a few KOhm @ Source signal
    Ych_OUT(Pin3) : Output Load 1uF

    INH(Pin6) and VEE(Pin7) and VSS(Pin8) are connected to GND


    We want to use CD4052B bringing out its performance but we don't have any know-how.
    We were looking for the some reference designs and detailed parameter measurement information on datasheet, but we couldn't.

    Do you have a solution ?

    Hi , I could find http://www.ti.com/lit/an/scha004/scha004.pdf app note which may be helpful for you .

    The input condition given is within the supported bandwidth for this device . However , 2.5V input would be below Vih level for the device at 5V Vdd ,so need to lower your Vdd level .Note that the input going below -0.5V can damage the device if drawing excessive ground (ESD)diode current . The app note in the datasheet of CD4052B and the detailed description should be very helpful too . 

    The VEE ,VSS and INH can be connected to gnd .
