The MAX4800CTM+ are highly versatile analog switches, multiplexers and demultiplexers featuring low on-resistance and low Ron variation with-change in VDD. They offer low charge injection, low quiescent current and low power consumption. The switch can be operated with up to ±40V of independent power supplies and their flexibility extends to providing various logic families at the control logic terminals. These switches are available in a small package size offering a wide range of analog switch configurations, making them suitable for a variety of applications.

Application Field of MAX4800CTM+

The MAX4800CTM+ is a versatile quad multiplexer/analog switch designed to handle analog signals within ±40V of independent power supplies. It is suitable for a variety of high-performance applications including data acquisition systems, high-speed sampling and control, instrumentation amplifiers and programmable gain amplifiers, analog switching, and voltage level shifting. The device also provides good immunity to ElectroMagnetic Interference (EMI) thanks to its design robustness and large total IO pins pitch.

Due to its low ON-resistance, low Ron variation with change in VDD, low charge injection, and low quiescent current, the MAX4800CTM+ is ideal for applications requiring highly reliable, low-distortion switching. Its high reliability and wide voltage range make it suitable for automotive and industrial applications. Its package size also reduces board space and system cost, making the MAX4800CTM+ suitable for applications using space-constrained designs.

Working Principle of MAX4800CTM+

The MAX4800CTM+ has four independently-selectable analog switches/multiplexers, each with a low ON-resistance of 8Ω (typically). The device also features a low Ron variation with a maximum of ±3% with a change in VDD from 0V to ±25V. The MAX4800CTM+ can select between a common node or one of the four input lines and eachswitch is controlled by a single logic input. The logic inputs can accept different logic families, including TTL, DTL, CMOS, and open collector logic.

The MAX4800CTM+ provides good immunity to EMI and ESD noise, due to its large pitch pins, making it suitable for applications in polluted environments. Additionally, its internal circuitry ensures that there can be no latch-up and its high linearity ensures no crosstalk and low distortion in the output signal.

The MAX4800CTM+ has a low quiescent current of 5uA (typically), resulting in low-power performance. Its wide power supply range can facilitate complex design requirements while its package size reduces board space and system cost. With the MAX4800CTM+, switching voltages can be changed with just one logic input, eliminating the need for multiple supplies in the same system.
