Texas Instruments TS5A3159ADCKR

Overview

TS5A3159ADCKR from Texas Instruments is a single-pole double-throw (SPDT) analog switch optimized for low-distortion audio and video signal routing in portable systems. It delivers 1.1 Ω typical ON-state resistance at 5 V, break-before-make switching, 100 MHz bandwidth, and operates from 1.65 V to 5.5 V supply - enabling use in battery-powered smartphones and USB-C audio adapters.

For engineers reviewing the TS5A3159ADCKR datasheet, TS5A3159ADCKR pinout, TS5A3159ADCKR application, or TS5A3159ADCKR 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 5.5-V-tolerant control inputs compatible with mixed-voltage logic interfaces.

Technical Context

The TS5A3159ADCKR implements a CMOS transmission-gate architecture with matched P/N channel sizing to ensure <0.1 Ω ON-resistance matching between NC and NO paths. Its break-before-make timing is hardwired via internal delay circuitry - not software-configurable - and guarantees no signal shorting during state transitions across the full –40°C to 85°C operating range.

It supports rail-to-rail analog signal handling (0 V to V+) with low charge injection (–4 pC min. at 1.8 V), minimal THD (0.004% at 5 V), and high off-isolation (–64 dB at 1 MHz), making it suitable for precision multiplexing in ADC front-ends and stereo headphone switching where crosstalk and distortion must be minimized.

FAQ

What is the maximum supply voltage rating for TS5A3159ADCKR?

The absolute maximum supply voltage (V+) for TS5A3159ADCKR is 6.5 V, but the 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. All specifications - including ON-resistance, THD, and bandwidth - are guaranteed only within the 1.65–5.5 V range per the official TI datasheet revision F.

Does TS5A3159ADCKR support true break-before-make switching across all supply voltages?

Yes, TS5A3159ADCKR guarantees break-before-make behavior across its entire 1.65–5.5 V supply range. At 1.8 V, tBBM is 22 ns (max); at 3.3 V, 40 ns (max); and at 5 V, 20 ns (max). This is achieved through internal analog timing circuitry - not dependent on external components - ensuring no signal shorting between NC and NO terminals during state transitions.

Can TS5A3159ADCKR handle analog signals beyond the supply rails?

No, TS5A3159ADCKR does not support overvoltage or negative signal handling. Its analog signal range is strictly limited to 0 V to V+ (rail-to-rail). Applying voltages outside this range - even briefly - violates Absolute Maximum Ratings and may cause latch-up or permanent damage. For bipolar or extended-range signals, external clamping or a different switch family (e.g., TMUX series) is required.

What is the thermal resistance (RθJA) of the TS5A3159ADCKR in its SC70-6 package?

The junction-to-ambient thermal resistance (RθJA) for TS5A3159ADCKR in the SC70-6 (DCK) package is 259°C/W, as specified in TI's thermal information table. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad). In high-density layouts or sealed enclosures, actual junction temperature rise will be higher - derating is recommended above 60 mW total power dissipation.

Is TS5A3159ADCKR pin-compatible with the older TS5A3159 device?

Yes, TS5A3159ADCKR is terminal-compatible with the original TS5A3159 device per TI's datasheet Feature section. Both share identical SC70-6 pinout (NO-GND-NC-COM-V+-IN), same electrical interface, and backward-compatible timing. However, TS5A3159ADCKR includes process and ESD improvements - including enhanced latch-up immunity (>100 mA per JESD78 Class II) - making it the recommended drop-in replacement for new designs.
