TSX582

TSX582 is a high-performance analog switch manufactured by STMicroelectronics, designed for precise signal routing in complex electronic systems. It features low on-resistance (typically 1.3 Ω at V_DS = 0 V) and ultra-low charge injection, making it ideal for high-accuracy applications such as data acquisition and precision measurement circuits. The device operates from a single 3.3 V supply, ensuring compatibility with modern low-voltage digital systems while maintaining robust analog performance. This dual-channel analog switch includes two independent switches with complementary PMOS and NMOS transistors configured in a parallel topology to minimize distortion and improve linearity. Its low leakage current (less than 1 nA at 25°C) ensures minimal signal degradation during open-state conditions, critical for high-impedance sensor interfaces and sample-and-hold circuits. Additionally, the TSX582 offers fast switching times—typically 40 ns rise/fall time—enabling efficient multiplexing of signals in dynamic environments. The package is a compact 8-pin SO8, which supports easy integration into space-constrained designs. It is fully specified over the industrial temperature range (-40°C to +85°C), making it suitable for harsh operating conditions in automotive, industrial automation, and medical instrumentation. The device also features built-in ESD protection (±2 kV HBM), enhancing reliability in electrostatically sensitive environments. In applications such as multiplexed sensor arrays, programmable gain amplifiers, and automatic test equipment, the TSX582 provides reliable, low-distortion signal path switching without introducing significant offset or gain errors. Its CMOS-compatible control inputs allow direct interfacing with microcontrollers and logic families like TTL or LVTTL, simplifying system design. Furthermore, the switch’s symmetrical architecture ensures consistent behavior regardless of signal direction, improving versatility across bidirectional signal routing tasks. STMicroelectronics ensures quality and consistency through rigorous testing and process control, guaranteeing long-term stability and high yield in production environments. The TSX582 is an optimal choice for engineers seeking a robust, low-power, and high-precision solution for analog signal management in demanding real-world applications.
