ADG5408BRUZ

ADG5408 is a high-voltage latch-up immune 8-to-1 single-ended analog multiplexer built on CMOS process. BRUZ stands for industrial temperature rating and 16-lead TSSOP surface-mount package. This component is packed in tube form for laboratory debugging, circuit validation and small-batch batch production assembly.

This monolithic analog multiplexer routes one out of eight analog input channels to a shared single output port, controlled by three-bit binary address signals. A dedicated enable pin can shut down all internal switches simultaneously to cut off all signal paths when disabled.

The device supports flexible wide-range power supply schemes: dual bipolar supply ranges from ±9 V to ±22 V, single positive supply covers 9 V to 40 V, with absolute maximum supply voltage rated at 48 V. Analog input signals can swing fully between the negative and positive supply rails without clipping distortion.

It features ultra-flat on-resistance across the entire signal bandwidth, with typical on-resistance maintained at 13.5 Ω and maximum value limited to 14 Ω. Consistent resistance characteristic brings excellent linearity and extremely low total harmonic distortion, which fits audio signal switching perfectly. The 50 MHz -3dB bandwidth and fast switching timing also satisfy high-speed video signal routing demands.

Manufactured with trench dielectric isolation technology, the chip is fully latch-up proof under transient overvoltage and improper power sequencing conditions, eliminating the need for massive external protective circuits. It carries 8 kV HBM ESD protection on all pins to resist electrostatic surges in industrial environments.

No separate logic supply pin is required; internal voltage generation circuit automatically supplies power for digital logic blocks, and all control pins are compatible with 3 V logic voltage levels. Off-state leakage current is kept extremely low to minimize signal drift for precision measurement circuits. Break-before-make switching structure prevents momentary short-circuit between different input channels during channel toggling.

Encapsulated in compact 16-pin plastic TSSOP housing with narrow body width, occupying minimal PCB space for multi-channel data acquisition modules and portable instrument mainboards. Moisture Sensitivity Level is MSL1, so no time limitation exists for reflow soldering procedures after the vacuum sealed package is opened. Tube packaging allows convenient manual plug-in testing, parameter calibration and small-volume pre-production assembly.

The operating ambient temperature range spans from -40 °C to +125 °C, delivering stable continuous operation under severe temperature fluctuation and heavy electromagnetic interference in industrial workshops, power monitoring systems and field measurement equipment. Produced with lead-free semiconductor fabrication technologies, the component complies with RoHS 3 global environmental regulations. The highly integrated single-chip design simplifies multi-channel analog signal selection circuits and enhances long-term working reliability of industrial signal chains.
