Texas Instruments TS5A3159ADBVR

Overview

TS5A3159ADBVR from Texas Instruments is a single-pole double-throw (SPDT) analog switch optimized for low-distortion audio and video signal routing in portable electronics. It delivers 1.1 Ω typical ON-state resistance at 5 V, break-before-make switching, 5.5-V tolerant control inputs, and operates from 1.65 V to 5.5 V supply. Its <0.004% THD at 5 V enables high-fidelity audio path selection in smartphones and PDAs.

For engineers reviewing the TS5A3159ADBVR datasheet, TS5A3159ADBVR pinout, TS5A3159ADBVR application, or TS5A3159ADBVR equivalent, key selection criteria include guaranteed break-before-make timing (6 ns typ. at 5 V), power-down isolation (<1 μA COM OFF leakage at V+ = 0), and 18 pF OFF capacitance for minimal crosstalk in multi-channel routing.

Technical Context

The TS5A3159ADBVR implements a CMOS transmission-gate architecture with matched P- and N-channel FETs to achieve low r_on and excellent r_on flatness (0.15 Ω max at 5 V). Its control logic accepts 0–5.5 V input levels independent of V+, enabling direct interface with 1.8-V, 3.3-V, or 5-V microcontrollers without level shifting.

Break-before-make timing is enforced by internal delay circuitry that guarantees ≥6 ns minimum dead time between NC and NO channel disconnect/reconnect events - critical for preventing momentary shorting in audio multiplexing. Power-down mode isolates all ports when V+ = 0, supporting hot-swap and battery-backed system architectures.

FAQ

What is the maximum supply voltage rating for the TS5A3159ADBVR?

The TS5A3159ADBVR has an absolute maximum supply voltage (V+) rating of 6.5 V, but its recommended operating range is 1.65 V to 5.5 V. Operation above 5.5 V risks exceeding safe electrical limits and may degrade long-term reliability. The device is fully specified and characterized within the 1.65–5.5 V range, including all key parameters like r_on, THD, and switching times. Always observe the 5.5 V upper limit for functional operation.

Does the TS5A3159ADBVR support break-before-make switching across all supply voltages?

Yes, the TS5A3159ADBVR guarantees break-before-make behavior across its entire 1.65–5.5 V supply range. At 1.8 V, t_BBM is 22 ns (max); at 3.3 V, it is 9 ns (max); and at 5 V, it is 6 ns (max). This timing is internally enforced by dedicated delay circuitry and does not require external control - ensuring reliable channel separation in audio, video, and data routing applications regardless of system voltage.

Can the TS5A3159ADBVR be used with a 1.8-V microcontroller GPIO driving the IN pin?

Yes, the TS5A3159ADBVR supports 1.8-V logic directly: its V_IL (max) is 0.6 V and V_IH (min) is 1.5 V at 1.8-V supply, meaning a standard 1.8-V GPIO output (typically 0 V / 1.8 V) meets both thresholds with margin. Additionally, the IN pin is 5.5-V tolerant, so no level-shifting circuitry is needed even if the host MCU operates at higher voltages - simplifying interface design and reducing component count.

What is the OFF-state leakage current of the TS5A3159ADBVR when V+ = 0 V?

When V+ = 0 V (power-down mode), the TS5A3159ADBVR exhibits ≤1 μA maximum OFF leakage current at all terminals (NC, NO, COM) over –40°C to 85°C. Specifically, I_NC(PWROFF), I_NO(PWROFF), and I_COM(PWROFF) are each rated at –1 μA to +1 μA. This ultra-low leakage enables true signal isolation during battery-off conditions in portable devices, preventing unwanted current paths or signal bleed.

How does the TS5A3159ADBVR's ON-state resistance vary with signal voltage?

The TS5A3159ADBVR maintains excellent r_on flatness: at 5 V supply, r_on(flat) is ≤0.15 Ω across the full 0–5 V analog signal range (V_NO or V_VNC). This means resistance variation is negligible - e.g., r_on changes by <0.15 Ω whether the signal is near ground or near V+. Such flatness ensures consistent gain and minimal distortion in AC-coupled and DC-coupled analog paths, critical for high-fidelity audio and precision instrumentation.
