The MAX4800A/MAX4802A provide high-voltage switching on eight channels for ultrasonic imaging and printer applications. The devices utilize BCDMOS process technology to provide eight high-voltage low-charge-injection SPST switches, controlled by a 20MHz serial interface. The digital interface operates from a separate VDD supply from +2.7V to +6V. Features include flexible high-voltage supplies up to VPP - VNN = 200V, low-charge-injection, low-capacitance 22Ω switches, and DC to 10MHz analog-signal frequency. The MAX4800A/MAX4802A are drop-in replacements for the Supertex HV2203 and HV2303.
The MAX4800A and MAX4802A provide high‑voltage switching on eight channels for ultrasonic imaging and printer applications. They use a BCDMOS process and feature low‑charge‑injection SPST switches controlled by a 20 MHz serial (SPI) interface.
These devices operate from a wide range of high‑voltage supplies, are pin‑compatible replacements for Supertex HV2203/HV2303, and are available in 48‑pin TQFP, 26‑bump CSBGA, and 28‑pin PLCC packages. They are specified for commercial temperature ranges and include optional integrated bleed resistors on the MAX4802A version.
