What are the key features of TS5A3159ADBVTE4?
- Single-pole double-throw SPDT topology with normally-closed default state enabling fail-safe signal routing without active power
- 100 MHz analog bandwidth with up to 5.5 V supply compatibility supporting audio, video, and baseband RF signal switching
- 6-pin SOT-23 package with AEC-Q100 compliance providing a miniature, automotive-grade solution for signal multiplexing in space-constrained PCBs
What is TS5A3159ADBVTE4 used for?
The TS5A3159ADBVTE4 is used in portable audio equipment, medical instrumentation, and automotive infotainment systems where a single-pole double-throw analog switch is needed for signal path selection up to 5.5 V. Its 100 MHz bandwidth accommodates both audio-band signals and moderate RF baseband switching in test and measurement multiplexers. The normally-closed default position ensures that the signal path remains connected during power-off states, which is valuable in fail-safe sensor input routing for industrial control systems.

Frequently Asked Questions
What bandwidth and supply voltage range does TS5A3159ADBVTE4 support for SPDT signal switching?
The TS5A3159ADBVTE4 supports an analog bandwidth of 100 MHz and operates from a supply voltage up to 5.5 V. This combination allows the switch to handle audio, video, and low-frequency RF baseband signals without significant attenuation, making it suitable for a broad range of single-supply systems operating at 3.3 V or 5 V logic levels.
How does the normally-closed default position of TS5A3159ADBVTE4 benefit fail-safe circuit designs?
In a normally-closed SPDT switch, the default signal path remains connected even when no control signal or supply voltage is applied. This behavior is critical in fail-safe designs such as patient monitoring equipment or automotive sensor inputs, where losing the signal during a power glitch could trigger a fault condition. The TS5A3159ADBVTE4 maintains continuity through the NC contact without any holding current, saving power in low-energy standby modes.
When should a designer select TS5A3159ADBVTE4 over TS5A3159DBVT (non-A variant) for a new design?
The TS5A3159ADBVTE4 A-variant typically features improved on-resistance flatness and lower charge injection compared to the base TS5A3159 version, reducing distortion in precision analog signal paths. Designers working on 16-bit or higher ADC input multiplexers, where even small variations in on-resistance cause linearity errors, should prefer the A-variant to meet THD specifications below -90 dBFS at audio frequencies.
What PCB area does the 6-pin SOT-23 package of TS5A3159ADBVTE4 occupy, and why does that matter for wearables?
The 6-pin SOT-23 package measures approximately 2.9 mm x 1.6 mm, occupying roughly 4.6 mm² of PCB footprint. In wearable health monitors and hearable devices where the total PCB may be smaller than 10 cm², this miniature outline allows the switch to be placed adjacent to the sensor input with less than 1 mm of signal trace length, minimizing parasitic capacitance and preserving signal integrity at the 100 MHz bandwidth limit.
