Microchip Technology HV2918R4X High-Voltage Analog Switch
The HV2818/HV2918 are 32-channel high-voltage analog switches designed for low harmonic distortion and low charge injection without requiring high-voltage bias supplies. Operating with only +5V bias, they facilitate high-voltage pulsed signal passing, ideal for medical ultrasound imaging, piezoelectric transducer driving, and printing applications. Featuring integrated bleed resistors in the HV2918 for load voltage stability, these compact, pin-to-pin compatible devices support up to +100V pulsed signals, deliver a typical 6Ω ON resistance, and provide bandwidths up to 50 MHz for small signals, ensuring reliable high-voltage switching in demanding systems.
