Maxim Integrated MAX4656ESA+T Analog Switch

The Maxim Integrated MAX4656ESA+T is a high-performance, single-pole/double-throw (SPDT) analog switch that offers a perfect blend of low power consumption and high-speed operation. This precision switch is designed to operate from a single +1.8V to +5.5V power supply, making it highly versatile and suitable for a variety of applications including battery-powered devices, portable instrumentation, and communication systems.

Encased in a compact 8-pin NSOIC package, the MAX4656ESA+T boasts a low on-resistance of 35Ω (max) matched between channels to within 2.5Ω (max) and flat (0.5Ω max) over the specified signal range. This ensures minimal signal distortion and makes it an excellent choice for routing precision analog signals. The switch's on-resistance is also matched between the source and drain, and is flat over the full analog signal range, providing consistent performance and reliability.

The MAX4656ESA+T is designed with Maxim Integrated's advanced CMOS technology, which provides low power dissipation yet gives high switching speed. The switch's high off-isolation of -80dB at 1MHz minimizes crosstalk between channels, while the fast switching times (tON = 120ns and tOFF = 70ns) allow for rapid signal routing, making it ideal for sample-and-hold circuits and multiplexing applications.

Additional features of this analog switch include a break-before-make switching action that prevents momentary shorting when switching between channels. The MAX4656ESA+T also has an extended operating temperature range from -40°C to +85°C, ensuring stable operation in a wide range of environments.

The MAX4656ESA+T is RoHS compliant and is designed with a latch-up performance that exceeds 300mA per JESD78, ensuring robust performance against latch-up. With its combination of low power, high speed, and precision, the Maxim Integrated MAX4656ESA+T analog switch is an ideal solution for designers looking to improve the efficiency and performance of their analog signal routing.
