Frequently Asked Questions
What signal voltage range can the HV2818/R4X switch, and how does it compare to standard analog mux ICs?
The HV2818/R4X switches analog signals from -100 V to +100 V, far exceeding the ±5 V to ±15 V range of standard CMOS multiplexers. This ±100 V capability makes it suitable for ultrasound transducer selection, high-voltage ATE pin electronics, and industrial sensor switching where large signal amplitudes occur.
How does the 64-channel count of HV2818/R4X reduce system complexity in multi-channel test equipment?
With 64 SPDT channels in a single QFN-64 package, the HV2818/R4X replaces arrays of discrete relays or multiple smaller mux ICs, reducing PCB area and component count significantly. A single device can route 64 independent high-voltage signal paths, simplifying board routing and lowering BOM cost in ATE and data acquisition systems.
Which medical imaging or ultrasound design benefits most from the HV2818/R4X architecture?
Ultrasound front-end designs benefit most because the HV2818/R4X can select among 64 transducer elements at ±100 V, covering both transmit and receive switching in a compact form. Medical imaging arrays require fast, low-distortion channel selection across high-voltage signals, and the HV2818/R4X meets these requirements while fitting a QFN-64 footprint compatible with high-density PCBs.
What logic supply voltage does HV2818/R4X require and how does that affect microcontroller interface design?
The HV2818/R4X requires a logic supply between 3 V and 5.5 V, making it directly compatible with 3.3 V and 5 V microcontrollers and FPGAs without additional level-shifting circuitry. This wide range simplifies board-level integration and reduces the number of power rails needed in mixed-voltage systems.
