Microchip Technology HV2818R4X High-Voltage Analog Switch
The HV2818/R4X series are 32-channel, high-voltage analog switches designed for applications such as medical ultrasound, piezoelectric transducer driving, and non-destructive testing. They operate with only a +5V bias, handling high-voltage pulsed signals up to 100V, with low harmonic distortion and charge injection. Built in a compact 64-pin QFN package, these switches feature asymmetric topology for smaller size, high bandwidth up to 50 MHz, and low ON resistance of approximately 6Ω. They include integrated bleed resistors (HV2918 model) to prevent voltage buildup on capacitive loads, and are controlled via a serial interface, supporting daisy-chain configurations for multiple channels.
