Maxim Integrated MAX4722EUA+ Low-Voltage, Dual SPST Analog Switches

The Maxim Integrated MAX4722EUA+ is a highly efficient, dual single-pole single-throw (SPST) analog switch designed to operate from a single +1.8V to +5.5V supply. This versatile component is well-suited for a wide array of applications, ranging from battery-powered devices to portable consumer electronics due to its low power consumption and compact footprint.

The MAX4722EUA+ offers two normally open (NO) switches that feature low on-resistance of 100Ω (max) at a +5V supply, which ensures minimal signal distortion and power loss across the switch. This characteristic, combined with a high switching speed, makes the device an excellent choice for audio and video signal routing, data acquisition systems, and sample-and-hold circuits.

One of the standout features of the MAX4722EUA+ is its low power consumption, with a quiescent current of just 1µA (max) at +25°C. This makes it an ideal switch for power-sensitive applications. Moreover, the device's single supply operation simplifies the design process, eliminating the need for dual supplies commonly required by other analog switches.

The MAX4722EUA+ is available in a small 8-pin µMAX package, which is ideal for space-constrained applications. Its extended temperature range of -40°C to +85°C guarantees reliable performance in a variety of environmental conditions.

Additional features include fast switching times (tON = 30ns and tOFF = 20ns at +5V), which enable quick signal changes without significant delay. The device also provides high off-isolation and crosstalk attenuation, maintaining signal integrity by minimizing noise and interference between channels.

For design flexibility, the MAX4722EUA+ includes TTL/CMOS-compatible digital inputs, allowing it to interface seamlessly with a wide range of logic levels and controllers. This capability, combined with its robust performance characteristics, makes the MAX4722EUA+ a highly versatile and reliable solution for designers looking to incorporate efficient analog switching capabilities into their electronic designs.
