MAX4802CXZ+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4802CXZ+T is an 8-channel high-voltage analog switch utilizing BCDMOS technology. It operates with VPP/VNN supplies ranging from +100V/-100V to +40V/-160V, while the digital interface accepts a separate VDD supply from +2.7V to +13.2V. The device features low-charge injection SPST switches with a typical on-resistance of 22Ω at +25°C and 200mA current. Integrated 35kΩ bleed resistors discharge capacitive loads via the RGND pin. It provides -77dB off-isolation at 5MHz and includes a power-on reset function ensuring all switches open upon startup.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component matches the specific package configuration required for the design. Confirm that the integrated bleed resistor functionality aligns with the system's load discharge requirements. Ensure the ordering suffix corresponds to the correct tape-and-reel packaging format intended for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a direct replacement for the Supertex HV232 is required in existing designs. Consider the integrated bleed resistors if the application involves discharging piezoelectric transducers or similar capacitive loads without external components. Verify compatibility with the available high-voltage supply rails within the specified operational range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4800/MAX4801/MAX4802 family of low-charge injection, 8-channel, high-voltage analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4802 variant specifically distinguishes itself through the inclusion of internal bleed resistors, differentiating it from the MAX4800 and MAX4801 models which lack this feature.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4802CXZ+T serves as a pin-compatible replacement for the Supertex HV232. Designers should verify that the physical footprint and pinout of the target PCB accommodate the 26-bump CSBGA package dimensions accurately.
