Introducing the TS5A3357DCUR from Texas Instruments

The TS5A3357DCUR is a high-performance, single-pole double-throw (SPDT) analog switch that is a part of Texas Instruments' extensive switch and multiplexer portfolio. This particular device is designed to operate within a voltage range of 1.65 V to 5.5 V, which allows it to be used in a multitude of applications ranging from low-voltage operations to more standard 5 V systems.

One of the key features of the TS5A3357DCUR is its low on-state resistance (Ron) of typically 0.9 Ω at 2.7 V, which ensures minimal signal distortion and loss. This low resistance is maintained across the full input signal range, up to the maximum specified voltage. The device also boasts a high off-state isolation of -35 dB at 10 MHz, which is critical for preventing signal leakage when the switch is in the off position.

The TS5A3357DCUR is designed with break-before-make switching operation, which ensures that one channel is disconnected before another channel connects. This feature helps to prevent shorting when switching between channels and is particularly important in multiplexing applications.

This analog switch also features a low charge injection of 10 pC (max) and a low total harmonic distortion (THD) of 0.02% (typical), which makes it an excellent choice for audio and other signal processing applications where maintaining signal integrity is crucial. Furthermore, the device has an ESD protection of ±8 kV Human Body Model (HBM), which provides robustness and reliability in handling and operational environments.

The TS5A3357DCUR comes in a compact VSSOP-8 (DGK) package, making it suitable for space-constrained applications. The device is also specified for operation over the extended industrial temperature range of -40°C to 85°C, which allows it to be used in harsh environments.

With its combination of low on-state resistance, high off-state isolation, low charge injection, and robust ESD protection, the TS5A3357DCUR from Texas Instruments is an ideal choice for designers looking to incorporate a reliable and high-performing analog switch into their electronic projects.
