MAX4802CCM+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4802CCM+T is an eight-channel high-voltage analog switch utilizing BCDMOS technology. It features low-charge injection SPST switches with a typical on-resistance of 22Ω and supports analog signal frequencies from DC to 10MHz. The device operates with flexible high-voltage supplies where VPP - VNN can reach up to 200V, while the digital interface functions on a separate VDD supply ranging from +2.7V to +13.2V. Digital inputs are tolerant up to +13.2V independent of VDD. A key differentiator is the integration of 35kΩ bleed resistors on each switch terminal for capacitive load discharge. It includes power-on reset functionality and is housed in a 48-pin TQFP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official datasheet specifications. Confirm the package type matches the 48-pin TQFP configuration. Ensure the ordering suffix corresponds to the tape-and-reel packaging format indicated by the 'T' designation. Cross-reference the part number with authorized distributor catalogs to confirm current availability status and lead times.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage switching with integrated discharge capabilities is required. The MAX4802 is specifically chosen over the MAX4800 or MAX4801 due to its built-in bleed resistors, which simplify circuit design for capacitive loads like piezoelectric transducers. Ensure the application voltage differential between VPP and VNN does not exceed 200V and that the digital logic levels are compatible with the +13.2V tolerant inputs.

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. While the MAX4800 replaces the Supertex HV20220 and the MAX4801 replaces the HV20320, the MAX4802 variant is distinct due to its integrated bleed resistors, making it the direct replacement for the Supertex HV232. All variants share similar pinouts and serial interface controls but differ in internal termination features.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4802CCM+T serves as a pin-compatible replacement for the Supertex HV232FG. Designers should verify that the legacy component's performance requirements align with the MAX4802's electrical characteristics, particularly regarding on-resistance and leakage currents.
