MAX4800CXZ+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4800CXZ+ 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 interface. The device operates with high-voltage supplies ranging from VPP = +40V to VNN + 200V and VNN = -160V to -15V, while the digital interface uses a separate VDD supply from +2.7V to +13.2V. Key electrical parameters include a maximum on-resistance of 38Ω at ICOM = 5mA, off-isolation of -77dB at 5MHz, and charge injection of 820pC. It is housed in a 72-CSBGA (6x5.35) package and specified for commercial temperatures between 0°C and +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices as availability may be limited. Ensure proper handling procedures are followed due to humidity sensitivity requirements during storage and soldering processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with Supertex HV20220 is required. Consider the CSBGA package for space-constrained designs. Verify that the required high-voltage differential does not exceed 200V. Ensure the digital controller supports the necessary serial clock frequencies and voltage levels for DIN, CLK, LE, and CLR 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. The MAX4800 variant specifically serves as a drop-in replacement for the Supertex HV20220. Other family members include the MAX4801 (replacing HV20320) and MAX4802 (replacing HV232), which features integrated bleed resistors.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4800 is a pin-compatible replacement for the Supertex HV20220. Designers should verify pinout compatibility if substituting other devices in the same family, such as the MAX4802, which includes additional bleed resistor functionality.
