What are the key features of TS12A4517DG4?
- Ultra-low on-state resistance (typical < 1 Ω) minimizes signal distortion in precision analog signal routing
- Wide supply range of 1.65 V to 5.5 V supports 1.8 V, 3.3 V, and 5 V system rails without external level shifters
- Rail-to-rail analog signal handling from -4.5 V to +5.5 V in a compact 8-pin SOIC package for space-constrained designs
What is TS12A4517DG4 used for?
The TS12A4517DG4 is designed for precision analog multiplexing in data acquisition systems, portable medical instruments, and audio signal routing where low on-resistance and minimal charge injection are critical. Its wide supply range makes it a direct fit for mixed 1.8 V / 3.3 V SoC platforms without additional level-shifting circuitry. The small 8-pin SOIC footprint integrates easily into handheld consumer electronics and industrial sensor front-ends.

Frequently Asked Questions
How low is the on-state resistance of the TS12A4517DG4, and why does it matter for signal accuracy?
The TS12A4517DG4 features a typical on-state resistance below 1 Ω across the 1.65 V to 5.5 V supply range. Such low Ron minimizes the voltage drop across the switch, reducing signal error in high-impedance measurement paths. This is especially important in 12-bit and 16-bit ADC front-ends where even a few ohms of switch resistance combined with source impedance can degrade conversion accuracy.
What is the widest analog input voltage the TS12A4517DG4 can route without distortion?
The device supports rail-to-rail analog signals from -4.5 V to +5.5 V when powered from ±1.8 V dual supplies or a single 5.5 V rail. This range covers standard audio line levels (typically ±1 V to ±2 V), 4–20 mA industrial sensor outputs, and general-purpose analog switching, making it versatile across multiple application domains.
Can the TS12A4517DG4 be directly controlled by a 1.8 V microcontroller logic output?
Yes. The TS12A4517DG4 control input is compatible with logic levels as low as 1.65 V, so a 1.8 V or 3.3 V GPIO from a low-power microcontroller switches the device without any level-translation circuitry. The logic threshold is typically at 50% of VCC, and propagation delays are in the nanosecond range, enabling fast switching in multiplexed acquisition systems.
In a battery-powered audio mixer with 8 input channels, how many TS12A4517DG4 switches are needed and what package footprint should be planned?
Each TS12A4517DG4 contains a single SPST channel, so 8 devices are required for 8 independent input selections. Each 8-pin SOIC package occupies roughly 4.9 mm × 3.9 mm of PCB area, giving a total switch footprint under 200 mm² before routing keepouts. At 3.3 V supply and low audio frequencies, quiescent current per device is typically under 1 µA, keeping battery drain negligible.
