Specifications
Part Number Definition
ADG5234 refers to four-channel high-voltage latch-up-proof SPDT analog switch series manufactured by Analog Devices. BRUZ stands for 20-lead TSSOP surface mount package, shipped in tube packaging for prototype debugging and small-batch assembly.
Core Electrical Performance Parameters
This monolithic CMOS analog switch integrates four independent single-pole double-throw channels. Every channel adopts break-before-make switching mechanism to avoid transient short-circuit between signal paths during channel toggling. A global enable pin is equipped to power down all switch channels simultaneously when disabled.
The device supports flexible power supply schemes: single supply ranging from 9 V to 40 V, dual bipolar supply from ±9 V to ±22 V, suitable for high-amplitude industrial analog signal circuits. Typical on-resistance is 140 Ω with maximum 500 Ω tolerance, and continuous channel conduction current reaches 24 mA.
Trench isolation technology is adopted inside the chip to thoroughly eliminate latch-up risks even under severe input overvoltage conditions. It features ultra-low charge injection and parasitic capacitance, greatly minimizing signal glitch distortion, which satisfies strict precision demands of sample-and-hold circuits and high-resolution data acquisition systems.
Maximum supply quiescent current is limited to 55 μA for low power consumption. Off-state leakage current is extremely tiny below 100 pA, ensuring signal holding accuracy. High signal bandwidth and fast switching speed also support audio and medium-frequency video signal routing applications.
Packaging and Assembly Specifications
Packaged in compact 20-pin TSSOP surface mount housing with moderate dimensions to balance layout space and thermal performance. Moisture Sensitivity Level is MSL1, no time limitation is required for reflow soldering after vacuum package opening. Standard tube packaging is adopted, convenient for manual soldering, breadboard testing and small-volume prototype production.
Environmental and Compliance Standards
Wide industrial operating temperature range covers -40 °C to +125 °C, capable of stable continuous operation in industrial instrumentation, airborne electronics, automotive control modules and automated test equipment with harsh temperature and electromagnetic environments. Fabricated with lead-free construction, the component complies with RoHS environmental directives. The integrated multi-channel design simplifies multi-signal switching hardware layout and reduces overall system component count.
