TA100

TA100 is a high-performance, low-power analog switch manufactured by Microchip Technology, designed for precise signal routing in mixed-signal and digital systems. It features a single-pole, double-throw (SPDT) configuration with ultra-low on-resistance (typically 25 Ω), ensuring minimal signal distortion and efficient power handling across a wide range of applications. The device operates from a supply voltage of 1.8 V to 5.5 V, making it compatible with both low-voltage and standard logic levels. This analog switch integrates advanced CMOS technology to provide exceptional linearity, low leakage current (less than 1 nA), and fast switching speeds—typically under 100 ns—enabling reliable performance in high-speed data acquisition, sensor multiplexing, and audio signal routing. Its compact 6-pin SOT-23 package offers space-efficient integration into densely populated PCB designs, ideal for portable and battery-powered devices. The TA100 includes built-in protection features such as ESD immunity up to ±2 kV (HBM) and overvoltage tolerance, enhancing system reliability in harsh environments. It supports bidirectional signal flow, allowing flexible use in both input and output configurations without degradation in signal integrity. Additionally, the switch exhibits stable performance over temperature ranges from –40°C to +125°C, making it suitable for industrial, automotive, and consumer electronics applications. Common uses include automatic test equipment (ATE), medical instrumentation, smart meters, and communication modules where precision, low power consumption, and robustness are critical. By enabling dynamic signal path control with minimal insertion loss and crosstalk, the TA100 enhances system flexibility while reducing component count and overall design complexity. Its compatibility with industry-standard logic levels simplifies interface with microcontrollers, FPGAs, and other digital peripherals.
