Product details
Overview
TS5A3166 from Texas Instruments is a single-pole single-throw (SPST) analog switch optimized for low-distortion audio signal routing, featuring 0.9 Ω typical ON-state resistance at 5 V, 1.65 V to 5.5 V single-supply operation, and ±2000-V HBM ESD rating. It enables bidirectional analog signal switching in portable audio paths such as microphone or headset routing in notebook docking stations.
For engineers reviewing the TS5A3166 datasheet, TS5A3166 pinout, TS5A3166 application, or TS5A3166 equivalent, key selection criteria include ON-resistance flatness (<0.15 Ω), charge injection (1 pC at 5 V), THD (0.005% at 5 V), and 5.5-V-tolerant control input compatibility with mixed-voltage logic systems.
Technical Context
The TS5A3166 implements a CMOS transmission-gate architecture with rail-to-rail analog signal handling (0 V to V+), enabling distortion-free switching of audio and sensor signals without level-shifting. Its control logic accepts VIH ≥2.4 V (5 V supply) or ≥1.5 V (1.8 V supply), supporting direct interfacing with 1.8-V, 2.5-V, 3.3-V, and 5-V microcontrollers.
Thermal performance is characterized by RθJA = 252°C/W in the SC-70 (DCK) package, with guaranteed operation from –40°C to +85°C ambient. The device achieves –64 dB OFF isolation at 1 MHz and 200 MHz bandwidth in ON state, making it suitable for both DC-coupled audio and high-speed data path applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-state resistance (rON) | 0.9 Ω typ @ 5 V - enables minimal voltage drop and power loss in low-current analog paths |
| Analog signal range | 0 V to V+ - supports rail-to-rail signal switching without clipping or distortion |
| Supply voltage range | 1.65 V to 5.5 V - ensures interoperability across battery-powered and legacy 5-V systems |
| Control input tolerance | 5.5-V tolerant - allows direct connection to higher-voltage logic without level shifters |
| Total harmonic distortion | 0.005% @ 5 V - preserves audio fidelity in microphone and line-level signal routing |
| Charge injection | 1 pC @ 5 V - minimizes transient glitches during switching in precision sensor or DAC output paths |
| OFF isolation | –64 dB @ 1 MHz - suppresses crosstalk between adjacent signal channels in multiplexed systems |
Pinout & Package
TS5A3166DCKR uses the 5-pin SC-70 (DCK) package, measuring 2.00 mm × 1.25 mm, with exposed pad not present and moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO) | Normally Open analog terminal | Switched analog I/O node; connects to COM only when IN = HIGH |
| 2 (COM) | Common analog terminal | Bidirectional analog port; routes signal between NO and internal switch path |
| 3 (GND) | Analog/digital ground reference | Return path for analog signals and digital control; must be low-impedance for THD performance |
| 4 (IN) | Digital control input | Active-HIGH logic pin; 5.5-V tolerant, drives internal transmission gate |
| 5 (V+) | Positive supply rail | Provides bias for analog switch core; sets analog signal range (0 V to V+) |
Key Features
| Feature | Design Value |
|---|---|
| Low ON-resistance flatness | <0.15 Ω variation across full analog range - maintains consistent gain and impedance matching in audio amplifiers |
| Rail-to-rail analog operation | 0 V to V+ signal handling - eliminates need for external biasing in single-supply audio circuits |
| Ultra-low charge injection | 1 pC @ 5 V - prevents audible pop/click in microphone and headphone switching applications |
| High OFF isolation | –64 dB @ 1 MHz - isolates unused signal paths to prevent leakage-induced noise coupling |
| Wide supply compatibility | 1.65–5.5 V operation - supports Li-ion (3.0–4.2 V), 3.3-V logic, and legacy 5-V systems without redesign |
Applications
| Microphone Switching – Notebook Docking | Audio Signal Routing in Portable Devices |
|---|---|
Use Scenario: Selecting between integrated laptop mic and external docked mic while maintaining low-noise signal integrity. IC Role / Device Role / Timing Role: SPST analog switch controlling mic signal path; no timing constraints-static configuration on system boot or user command. Use Value: 0.9 Ω rON and 0.005% THD preserve SNR >95 dB; 5.5-V-tolerant IN pin interfaces directly with dock MCU GPIOs. |
Use Scenario: Routing stereo line-in/line-out signals between codec, amplifier, and headphone jack in smartphones or tablets. IC Role / Device Role / Timing Role: Bidirectional analog switch enabling flexible signal path reconfiguration; operates in static mode with <10 ns tON/tOFF. Use Value: 200 MHz bandwidth supports full audio spectrum (20 Hz–20 kHz); 19 pF CNO(OFF) minimizes capacitive loading on source. |
| Low-Voltage Data-Acquisition Systems | Communication Circuits with Analog Front-Ends |
Use Scenario: Multiplexing sensor outputs (e.g., temperature, pressure) into a shared ADC channel in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Precision analog switch enabling sequential sampling; requires low leakage (<20 nA OFF) to avoid measurement drift. Use Value: INO(OFF) ≤20 nA and ICOM(OFF) ≤20 nA ensure <0.01% gain error over 16-bit ADC full scale at 1.8 V supply. |
Use Scenario: Isolating RF transceiver analog baseband inputs during sleep mode to reduce standby current and noise coupling. IC Role / Device Role / Timing Role: Signal gate in analog front-end; switched ON/OFF under processor control to manage power states. Use Value: –64 dB OFF isolation blocks LO leakage; 0.4 μA ICOM(PWROFF) limits quiescent current in powered-off mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574DCKR | Higher rON (1.5 Ω typ @ 3.3 V), lower THD (0.002%), but requires minimum 3-V supply | Not suitable for 1.8-V systems; better for high-fidelity audio where supply ≥3 V is guaranteed | Select TMUX1574DCKR when THD <0.003% is mandatory and supply is stable ≥3 V |
| ADG801BRJZ-REEL7 | Lower rON (0.3 Ω typ @ 5 V), but only 1.8–5.5 V rated and no 5.5-V-tolerant control input | Requires level-shifter for 5-V logic interface; superior for ultra-low-loss paths where control voltage matches supply | Select ADG801BRJZ-REEL7 when minimizing rON is critical and control logic voltage equals V+ |
Compared with TMUX1574DCKR and ADG801BRJZ-REEL7, TS5A3166DCKR uniquely balances 5.5-V-tolerant control, 1.65-V minimum supply, and sub-1-Ω rON, making it optimal for mixed-voltage portable designs where flexibility and audio fidelity are jointly required.

FAQ
What is the maximum supply voltage for TS5A3166DCKR?
The absolute maximum supply voltage (V+) for TS5A3166DCKR is 6.5 V, but the recommended operating range is 1.65 V to 5.5 V. Operating beyond 5.5 V risks violating the specified electrical characteristics and may degrade reliability. All performance parameters-including rON, THD, and leakage-are guaranteed only within the 1.65–5.5 V range per the SCDS186E datasheet revision February 2018.
Does TS5A3166DCKR support bidirectional analog signal flow?
Yes, TS5A3166DCKR supports fully bidirectional analog signal flow between the NO and COM pins. Its CMOS transmission-gate structure imposes no directionality-signals pass equally well from NO to COM or COM to NO, provided the voltage remains within 0 V to V+. This enables flexible use in shared bus architectures and reversible sensor interfaces without redesign.
What is the typical ON-state resistance of TS5A3166DCKR at 3.3 V supply?
The typical ON-state resistance (rON) of TS5A3166DCKR at 3.3 V supply is 1.4 Ω, measured at VNO = 2 V and ICOM = –100 mA (per Section 6.6 of SCDS186E). This value reflects real-world performance in mid-range portable systems and is confirmed across –40°C to +85°C ambient temperature with full production lot testing.
Can TS5A3166DCKR be used with 1.8-V logic control signals?
Yes, TS5A3166DCKR accepts 1.8-V logic control signals: its VIL max is 0.6 V and VIH min is 1.5 V at V+ = 1.95 V, ensuring reliable turn-on with standard 1.8-V CMOS outputs. The 5.5-V-tolerant IN pin further guarantees robustness against overshoot or mixed-voltage noise without external protection circuitry.
How does TS5A3166DCKR perform in audio applications requiring low THD?
TS5A3166DCKR delivers 0.005% total harmonic distortion (THD) at 5 V supply with RL = 600 Ω and CL = 50 pF over 20 Hz–20 kHz, meeting high-fidelity audio requirements. This performance is sustained across supply voltages down to 1.8 V (0.055% THD), making TS5A3166DCKR suitable for both premium and cost-sensitive portable audio signal routing where distortion must remain below audible thresholds.
