  • RE: ADS1234: Sample code for self Offset calibration

    Resolved
    Bob, OK... That is what I have. I have 4 load cells connected, and am using 4 TS5A3166 switches to each load cell to ground. I did a test today over temperature, and I saw no difference in the temperature error profile (heating and cooling the PCB…

  • SN74LVC2G66-Q1: question about isolation between associated switch section

    TI Thinks Resolved
    Part Number: SN74LVC2G66-Q1 Other Parts Discussed in Thread: TS5A3166-Q1 Hi TI， For SN74LVC2G66QDCURQ1， when VCC power off， what is the impedence between associated switch section？if we want to keep the associated switch section isolated, must keep…

  • TS5A3167: Powered-Off Protection depending on V+

    Resolved
    Part Number: TS5A3167 Other Parts Discussed in Thread: TS5A3166 , , TMUX1574 Hello, I found this E2E post that talks about the TS5A3166: e2e.ti.com/.../660359 The applications engineer mentioned the powered-off protection works properly when V+ is…

  • RE: SN74LVC1G66-Q1: Max Peak Current and On-state resistance

    1. The datasheet specifies r on as 30 Ω max. 2. The datasheet specifies I T as 50 mA max. Consider using the TS5A3166-Q1 instead.

  • RE: TMUX1574: Max channel current

    Resolved
    The voltage drop over that switch would be 64 mA × 5 Ω = 0.32 V. The on-resistance of the switch should be as small as possible. Consider the TS3A44159 if the voltage and frequency match. Otherwise, use a larger device with multiple channels in parallel…

  • RE: TS5A22364: Selecting an SPDT switch to multiplex very low amplitude EEG signals (<10 uV level) with negligent noise?

    Raza, Just to clarify because I realize I misspoke on the last post. I said 'can handle negative supply rails' but I meant 'can handle negative data signals'. Unfortunately, we won't have a similar SPST switch that has negative voltage carrying capabilities…

  • RE: TPS2087: TPS2087

    Nandini, You can use the switch selection tool on Ti.com to find switches that are 1:1 configuration, 1-channel, Ron <1 ohm, and I/O continuous current >5mA. After filtering for these parameters I found these options. The TS5A3167 is active low and…

  • ADS1232: analogue part does not shut

    Resolved
    Part Number: ADS1232 Other Parts Discussed in Thread: TS5A3166 Hi, I use the ads1232 with DVDD 3.3V and AVDD 6V with referential configuration. If I let the software shutdown the device /PWDN the device shuts normally. But If I accidentally remove…

  • RE: TS5A3160: issue with the bidirectional nature of the IC

    Den, What is driving your 3.3 V rail? If the TS5A3160 V+ rail is held at 0V and not floating the path from NC to COM should be Hi-Z. I suspect that the V+ node is floating in which the 5V rail in your system is able to pass from NC to COM and place…
