Typical Applications
TS3A5018PWR is suitable for 6 applications: Audio Signal Routing, Data Acquisition Systems, Communication Interfaces, Test and Measurement Equipment, Portable and Battery-Powered Devices, Industrial Control Systems.
Audio Signal Routing
The TS3A5018PWR is ideal for audio signal routing in portable devices and mixing consoles. Its low ON-state resistance of 10 Ξ© minimizes signal attenuation, while low charge injection reduces audible clicks during switching. The wide supply range of 1.8V to 3.6V allows operation from single-cell batteries. In a typical audio path, the switch can route between multiple sources (e.g., microphone, line-in) to a single ADC input. The fast switching speed (5ns) ensures minimal signal delay, and the bidirectional capability allows flexible signal flow. For best performance, use low-impedance loads and place decoupling capacitors near the V+ pin.
Recommended
Data Acquisition Systems
In data acquisition systems, the TS3A5018PWR can multiplex multiple analog sensor signals into a single ADC channel. Its 10 Ξ© ON-state resistance and low charge injection preserve signal integrity, while the 1.8V-3.6V supply range is compatible with modern microcontrollers. The quad SPDT configuration allows routing of up to four differential or single-ended signals. The fast switching speed (5ns) enables high-throughput sampling. For accurate measurements, ensure the source impedance is low relative to the switch resistance. The enable pin can be used to power down the switch when not sampling, saving power in battery-operated loggers.
Recommended
Communication Interfaces
The TS3A5018PWR is suitable for routing signals in communication interfaces such as UART, SPI, or I2C. Its bidirectional capability allows signals to pass in either direction, and the low ON-state resistance (10 Ξ©) minimizes signal degradation. The wide supply range (1.8V-3.6V) supports various logic levels. The fast switching speed (5ns) is ideal for high-speed data lines. In a typical application, the switch can select between multiple peripherals sharing a single bus. The enable pin provides a simple way to isolate the bus when not in use. Proper termination and decoupling are recommended to maintain signal integrity.
Recommended
Test and Measurement Equipment
In test and measurement equipment, the TS3A5018PWR can route signals to different measurement paths. Its low ON-state resistance (10 Ξ©) and fast switching (5ns) enable accurate signal routing with minimal distortion. The 1.8V-3.6V supply range is compatible with benchtop instruments. The quad SPDT configuration allows multiplexing of multiple test points. The low charge injection reduces glitches during switching, which is critical for precise measurements. For high-frequency signals, consider the bandwidth limitations. The enable pin can be used to isolate the measurement circuit when not in use.
Recommended
Portable and Battery-Powered Devices
The TS3A5018PWR is well-suited for portable devices due to its low power consumption and wide supply range (1.8V-3.6V). The enable pin allows the switch to be powered down when not in use, extending battery life. The compact 16-TSSOP package saves PCB space. In a typical portable device, the switch can route audio, sensor, or communication signals. The low ON-state resistance (10 Ξ©) ensures efficient signal transfer. The fast switching speed (5ns) supports responsive user interfaces. For optimal power management, use the enable pin to disable the switch during standby modes.
Recommended
Industrial Control Systems
In industrial control systems, the TS3A5018PWR can route analog signals from sensors to controllers. Its wide supply range (1.8V-3.6V) and operating temperature range (-40Β°C to +85Β°C) make it suitable for harsh environments. The low ON-state resistance (10 Ξ©) ensures accurate signal transmission. The quad SPDT configuration allows multiplexing of multiple sensor inputs. The fast switching speed (5ns) enables real-time control. For industrial applications, consider adding ESD protection. The enable pin can be used to isolate the switch during maintenance or fault conditions.

Key Differentiators
- Low ON-state resistance of 10 Ξ© (vs MAX4535)
- Fast switching speed (5ns turn-on, 3.5ns turn-off) (vs MAX4535)
- Wide supply voltage range (1.8V to 3.6V) (vs ADG884)
Design Notes
The TS3A5018PWR operates from 1.8V to 3.6V. Ensure the V+ pin is properly decoupled with a 0.1uF ceramic capacitor placed as close to the pin as possible. For noisy environments, add a 10uF bulk capacitor. The enable pin can be tied to V+ for always-on operation or controlled by a GPIO for power saving.
For optimal signal integrity, keep traces short and use a solid ground plane. The 10 Ξ© ON-state resistance can cause attenuation in high-impedance circuits; use low-impedance loads. Place decoupling capacitors near the V+ pin and ensure proper grounding of the GND pins.
Do not exceed the supply voltage range of 3.6V. Ensure signals do not exceed V+ to avoid latch-up. The enable pin is active high; when low, all switches are off. Verify the pinout matches your PCB layout, especially the SEL pin which selects between B1 and B2 paths.
