MAX4800ACCM+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4800ACCM+ is an eight-channel, single-pole single-throw (SPST) high-voltage analog switch manufactured by Analog Devices Inc. utilizing BCDMOS process technology. It features a 20MHz SPI-compatible serial interface with an internal 8-bit shift register and programmable latch. The device supports flexible high-voltage supplies where VPP - VNN can reach up to 200V, accommodating configurations such as +100V/-100V, +185V/-15V, or +40V/-160V. The digital logic operates on a separate VDD supply ranging from +2.7V to +6V, with inputs tolerant up to +6V. It provides low charge injection and low capacitance switches with a typical on-resistance of 22Ω at 200mA. The component is housed in a 48-pin LQFP package and is specified for the commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and RoHS compliance status. The '+' suffix indicates lead-free and RoHS-compliant manufacturing. Confirm availability through authorized distributors, as stock levels may vary. Ensure the selected variant matches the required pin count and thermal dissipation characteristics for the target PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring high-voltage analog switching with minimal signal distortion. Verify that the application's supply voltages fall within the specified VPP and VNN limits. Consider the 48-pin LQFP package constraints regarding thermal resistance and board space. Ensure the host controller supports the required SPI timing parameters for reliable data transfer.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4800A/MAX4802A family of low-charge-injection, high-voltage analog switches. The MAX4800A variant lacks integrated bleed resistors, whereas the MAX4802A includes them. Both variants serve as pin-compatible replacements for legacy Supertex HV2203 and HV2303 devices, respectively, facilitating direct upgrades in existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4800ACCM+ serves as a drop-in replacement for the Supertex HV2203FG-G. When substituting, verify that the pinout compatibility remains intact and that the new device's electrical characteristics meet the system requirements.
