Product details
Overview
TS5A3160DBVR from Texas Instruments is a single-pole double-throw (SPDT) analog switch optimized for low-distortion audio routing in portable systems. It delivers 1.1 Ω typical ON-state resistance at 5 V, ±64 dB OFF isolation at 10 MHz, and 0.004% THD at 5 V - enabling high-fidelity signal path selection in mobile phones and portable instrumentation.
For engineers reviewing the TS5A3160DBVR datasheet, TS5A3160DBVR pinout, TS5A3160DBVR application, or TS5A3160DBVR equivalent, key selection criteria include make-before-break timing (7 ns typ), 1.65–5.5 V single-supply operation, 5.5-V-tolerant control input, and SOT-23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The TS5A3160DBVR implements a CMOS transmission-gate architecture with complementary P/N channel pairs per switch path, enabling bidirectional analog signal flow and rail-to-rail voltage handling (0 V to V+). Its internal logic interprets IN as a digital select: low connects COM to NC, high connects COM to NO.
It features true powered-off isolation (ICOM(PWROFF) ≤ 0.2 μA at V+ = 0 V), specified make-before-break switching (tMBB ≤ 12 ns), and charge injection of only 36.5 pC at 5 V - critical for minimizing glitch-induced pop/click in audio DAC/ADC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-state resistance | 1.1 Ω typ at 5 V - ensures minimal insertion loss and signal attenuation in audio paths |
| Supply voltage range | 1.65 V to 5.5 V - supports direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic/system rails |
| Control input tolerance | 5.5-V tolerant - allows use with higher-voltage controllers without level shifting |
| THD + Noise | 0.004% at 5 V - preserves audio fidelity in portable headphone/speaker amplifiers |
| OFF isolation | –64 dB at 10 MHz - prevents crosstalk between unused signal paths in multi-source systems |
| Charge injection | 36.5 pC at 5 V - limits voltage glitch on sensitive nodes like ADC reference inputs |
| Make-before-break time | 7 ns typ - avoids momentary signal discontinuity during source switching |
Pinout & Package

| 3 (NC) | Normally closed switch port | Connected to COM when IN = low; remains open when IN = high |
| 4 (COM) | Common analog terminal | Bidirectional I/O node routed to either NC or NO based on IN state |
| 5 (V+) | Positive supply | Single power rail (1.65–5.5 V); powers analog switch core and control logic |
| 6 (IN) | Digital control input | CMOS-compatible logic select: low → COM↔NC, high → COM↔NO |
Key Features
| Feature | Design Value |
|---|---|
| Low ON-resistance matching | Δron ≤ 0.1 Ω - minimizes gain mismatch in differential or stereo signal routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574DBVR | Lower ron (0.5 Ω typ), but requires dual supply (±2.5 V) or 3.3-V single supply; no 1.65-V operation | Optimized for high-speed test equipment, not portable battery-powered audio | Select if lower ON-resistance is critical and supply rail ≥3.3 V is guaranteed |
| ADG884BRMZ-REEL7 | Higher ron (0.55 Ω min), wider temp range (–40°C to +125°C), but no 5.5-V-tolerant IN | Suitable for automotive cabin audio, not consumer mobile where 5-V-tolerant control simplifies design | Select for extended temperature or AEC-Q200 compliance; avoid if interfacing with 5-V microcontrollers |
Compared with TMUX1574DBVR and ADG884BRMZ-REEL7, the TS5A3160DBVR uniquely balances ultra-low THD, 1.65-V operability, and 5.5-V-tolerant control - making it optimal for cost-sensitive, battery-powered portable audio where supply headroom is limited and controller voltage may exceed switch V+.

FAQ
What is the maximum supply voltage rating for the TS5A3160DBVR?
The TS5A3160DBVR has an absolute maximum supply voltage (V+) of 6.5 V, but its recommended operating range is 1.65 V to 5.5 V. Operating above 5.5 V risks exceeding electrical specifications and may degrade reliability. The device is rated for 5.5-V-tolerant digital inputs regardless of V+, enabling safe interfacing with 5-V controllers even when V+ is 1.8 V.
Does the TS5A3160DBVR support make-before-break switching, and what is its typical timing?
Yes, the TS5A3160DBVR is explicitly specified for make-before-break operation. At 5 V supply, its typical make-before-break time (tMBB) is 7 ns, with a maximum of 12 ns over temperature and voltage. This ensures continuous signal connection during switching - critical for avoiding audible clicks in audio paths and data glitches in sampled systems.
Can the TS5A3160DBVR operate with a 1.8-V supply, and how does performance change?
Yes, the TS5A3160DBVR operates down to 1.65 V. At 1.8 V, typical ON-resistance rises to 2.5 Ω, THD increases to 0.06%, and turn-on time extends to 13 ns. However, it retains full functionality including 5.5-V-tolerant IN, powered-off isolation, and ±64 dB OFF isolation - making it viable for ultra-low-power wearable designs where supply headroom is constrained.
What is the significance of the NC and NO pin labeling on the TS5A3160DBVR?
NC (pin 3) is the normally closed port: COM connects to NC when the IN control input is logic low. NO (pin 1) is the normally open port: COM connects to NO when IN is logic high. This labeling reflects default states under static control conditions - not physical relay behavior - and confirms the device's SPDT topology with unambiguous signal routing directionality.
How does the TS5A3160DBVR handle powered-off isolation, and why is it important?
The TS5A3160DBVR provides powered-off isolation by limiting COM, NC, and NO OFF-leakage currents to ≤0.2 μA when V+ = 0 V. This prevents signal bleed-through and back-powering of upstream circuits during system sleep modes - essential for extending battery life in portable devices and maintaining signal integrity in multi-rail systems where one domain may be powered down while others remain active.
