MAX4800CTM+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4800CTM+T is an eight-channel high-voltage analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It utilizes BCDMOS technology to provide low-charge-injection SPST switches controlled via a serial digital interface. The device supports wide high-voltage supply ranges, including VPP/VNN combinations of +100V/-100V, +185V/-15V, and +40V/-160V, with a maximum differential voltage of 200V. The logic interface operates on a separate VDD supply from +2.7V to +13.2V. Key electrical parameters include a typical on-resistance of 22Ω at +25°C, off-isolation of -77dB at 5MHz, and quiescent current of 10µA. It is specified for commercial operation between 0°C and +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CTM' against official documentation, as standard datasheets list CCM (TQFP), CQI (PLCC), and CXZ (CSBGA). Confirm RoHS compliance status associated with the '+' designation. Check component lifecycle status, as older Maxim parts may be discontinued or subject to limited availability. Ensure the package type matches the required PCB land pattern.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a direct replacement for Supertex HV20220 is required in ultrasound or printer designs. Consider the MAX4802 variant if integrated bleed resistors are needed for capacitive load discharge. Verify that the system's high-voltage requirements fall within the supported VPP/VNN ranges and that the serial interface timing meets the controller's clock speed capabilities.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4800CTM+T belongs to the MAX4800/MAX4801/MAX4802 family of low-charge injection, 8-channel, high-voltage analog switches. This family is designed for applications requiring robust high-voltage switching with precise digital control. The MAX4800 specifically targets markets needing compatibility with legacy Supertex components while offering modern CMOS performance characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4800 is a pin-compatible replacement for the Supertex HV20220. Designers should verify pinout compatibility and electrical parameter margins before substitution.
