MAX4802ACCM+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4802ACCM+T is an eight-channel high-voltage analog switch IC manufactured by Analog Devices Inc. It utilizes BCDMOS technology to provide low-charge-injection SPST switches controlled via a 20MHz serial interface. The device operates with flexible high-voltage supplies ranging from VPP = +40V to (VNN + 200V) and VNN = -160V to -15V, while the digital logic supply (VDD) ranges from +2.7V to +6V. Key electrical parameters include a typical on-resistance of 22Ω at +25°C, off-isolation of -77dB at 5MHz, and integrated 35kΩ bleed resistors for load discharge. It is housed in a 48-pin LQFP package and specified for commercial temperatures between 0°C and +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated 35kΩ bleed resistors on each switch terminal to discharge capacitive loads
• Pin-compatible replacement for Supertex HV2303 devices
• Low-charge-injection and low-capacitance SPST switches
• Power-on reset function ensures all switches are open upon power-up

Analog Switches, Multiplexers, Demultiplexers Applications

• Ultrasound imaging systems
• Printer applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix '+T' corresponds to tape-and-reel packaging as indicated in standard Maxim Integrated conventions, though the provided datasheet explicitly lists 'MAX4802ACCM+' without the T suffix in the selector guide. Confirm RoHS compliance status based on the '+' designation. Ensure the component source is an authorized distributor or manufacturer representative to guarantee authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4802ACCM+T when integrated bleed resistors are required to safely discharge piezoelectric transducers or other capacitive loads. This variant is specifically designed as a drop-in replacement for the Supertex HV2303. Ensure the application voltage differential does not exceed 200V and that the digital controller supports the required 20MHz SPI timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4800A/MAX4802A family of high-voltage analog switches. The MAX4802A variant is distinguished by the inclusion of internal bleed resistors, whereas the MAX4800A lacks this feature but shares identical switching characteristics. Both variants serve as direct replacements for legacy Supertex HV2203 and HV2303 components in existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4802ACCM+T is a pin-compatible replacement for the Supertex HV2303FG-G. Designers upgrading from older generations should verify that the new device's 20MHz serial interface timing requirements are compatible with the host controller.
