TMUX9616: Ron characteristics (vs. VD/VS, T, VDD/VSS) and leakage current

Richie Ellingham
Prodigy 10 points
Part Number: TMUX9616

I'm wanting to upgrade a circuit for an electrical impedance tomography device.

The datasheet for the TMUX9616 is missing some bits of data I need, before incorporating into my design which will operate at VDD/VSS = +/- 20V.

1. The Ron characteristic plot for VDD/VSS = +/-20V

2. The Ron characteristic plot for VDD/VSS = +/-20V at temperature 0 - 80°C

3. Leakage current characteristic plot for VDD/VSS = +/-20V and a range of VD/VS values 0 -20V

 

Where can I find this data? Is there a more comprehensive datasheet available?

    Hello Richie,

    Please see Ron Plot below, this is from section 6.9 of the datasheet. 

    The Ron of the device is pretty flat, but as you can see at ±20V the Ron value ranges from 10Ω to 22.5Ω depending on the temperature. 

    For the current leakage spec, unfortunately we don't have a plot to share. I can provide the measured values, which hopefully helps. 

    Temperature Voltage Off Leakage On Leakage
    25°C ±20V -192nA to 200nA -800nA to -745nA
    85°C ±20V -127nA to 122nA -842nA to -798nA
    125°C ±20V -109nA to 117nA -869nA to -850

    The data in the table above was captured with VDD = 20 and VSS = -20. The VD/VS values are from 0V to 20V. 

    There isn't a more comprehensive datasheet, this data stored internally.

    Thanks,

    Nir

    Thanks for the info.

    Is there any data on the Ron curve for a range of drain values? Somewhat like this: 

    Ok that leakage current data is useful.

    Hello Richie,

    Unfortunately, we don't have Ron curves for a range of drain values, but we do have some data.

    At 25°C; VDD = 110V; VS = -8V to 10V and VD = -8V to 10V; the Ron value ranges from 12.3Ω to 12.7Ω. 

    I hope this information is sufficient enough.

    Thanks,

    Nir
