TS4102ITQ1633

Overview

The TS4102ITQ1633 is a triple single-pole/double-throw (SPDT) analog switch manufactured by Silicon Labs. It operates with a supply voltage range of 0.8 V to 5.25 V and supports input signal swings up to 5.25 V, independent of the supply rail. The device features an on-resistance of 80 Ω typical at higher voltages, with less than 1% flatness variation across the entire signal swing. Supply current is 675 nA, and leakage currents are guaranteed below 0.5 nA. It functions within a temperature range of –40 °C to +85 °C and is housed in a 16-pin, 3 mm x 3 mm TQFN package.

Feature Summary

• Triple SPDT configuration with three independent switching channels
• "Rail-to-Rail Plus" capability allowing input signals to exceed supply voltage
• Ultra-low power consumption with 675 nA supply current
• High linearity maintained by less than 1% on-resistance variation

Applications

• Low-voltage battery-operated equipment
• Precision measurement systems
• Audio signal routing
• Switched-capacitor voltage doubler circuits

Procurement Notes

Verify the specific ordering suffix for packaging requirements. Adding the letter "T" to the part number indicates tape and reel packaging, whereas the standard suffix denotes tube packaging. Confirm that the component meets RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when multiple independent signal paths require switching under low-voltage conditions. Ensure the application can accommodate the break-before-make delay characteristic. Verify that the load impedance does not generate excessive charge pump spikes without appropriate filtering capacitors.

Part Context

This device belongs to the TS410x family of analog switches, which also includes the TS4100 multiplexer and the TS4101 dual multiplexer. All members share identical electrical characteristics, pinouts, and the "Rail-to-Rail Plus" architecture designed for high-fidelity signal handling.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation.

FAQ

How does the TS4102 handle input voltages exceeding the supply voltage?

The device utilizes a "Rail-to-Rail Plus" architecture where the input voltage is independent of the supply voltage, allowing signals up to 5.25 V even if the supply is lower.

What is the recommended method to suppress charge pump spikes?

If high input or output impedances cause concern regarding transient spikes, placing a 500 pF capacitor to ground at the input or output will effectively suppress them.

What is the maximum off-isolation performance of the TS4102?

At a frequency of 10 kHz, the off-isolation is approximately -88 dB.
