MAX4534ESD+T

Interface - Analog Switches, Multiplexers, Demultiplexers

The MAX4534ESD+T is a low-voltage, high-speed, 1-of-2, single-pole double-throw (SPDT) analog switch that operates from 1.7V to 5.5V. The device has quick switching time of 8ns, making it suitable for a variety of high-speed applications including filtered switched-capacitor networks, sample-and-hold circuits, automatic-gain-control circuits and analog-to-digital converters.

The switch has two independent channels that are designed with ESD protection of up to 14KV human body model (HBM) and 2KV-charged-device model (CDM). Both channels have low leakage of 0.5nA (max) and 0.2nA (max) for the MAX4534ESD+T and the MAX4534+T, respectively. The switch supports wider voltage range from 1.7V to 5.5V that makes it perfectly suitable for all low-voltage applications specific to Li-ion battery-powered products.

Working Principle

The MAX4534ESD+T consists of a digital input and two analog switches. The digital input determines which analog switch is connected to the output and the other switch is internally connected to the GND pin. The device’s cross-conduction and power dissipation is low, making it suitable for low-power and space-constrained applications. In addition, the output can be disabled or switched off by applying a logic high to the pin.

The switch has an on-resistance of 0.9Ω (max). The device is ESD protection on input and output pins to eliminate damage caused by sudden heavy static discharges and ensures stable signal performance. The driver neutrality design ensures minimal biasing effects during the switch transitions.

Application Field

The MAX4534ESD+T switch is ideally suited for signal switching applications in consumer electronics, automotive electronics, medical electronics, industrial instrumentation, and so on. The power rating of 1W is also suitable for handling small signal switches for industrial control and other applications in audio visual, gaming, telecom and networking.

The device offers functional flexibility and performance for portable device applications such as digital cameras, camcorders, portable media players and other consumer electronics. It is also used in medical electronics equipment such as CT scanners, medical imaging systems, monitoring systems, and so on. The device can also be used in automotive electronics such as airbag deployment control, air conditioning systems, and so on.

The MAX4534ESD+T offers excellent ESD immunity and optimal audio performance. The device also offers low supply current and low signal distortion. The device consumes only 2μA of current at its quiescent state and only 4μA (max) in its active state. The MAX4534ESD+T can support multiple switchable analog signals with a wide signal range of 0V to 5V.

The on-resistance of the device is 0.9Ω (max), which is low enough for use in high-speed switching applications. The fast switching time of 8ns (max) also makes the MAX4534ESD+T suitable for applications where rising times are crucial. The device is also tolerant to capacitive loads, making it suitable for use in capacitive load switching applications.
