Maxim Integrated MAX4625EZT Low-Voltage, Single SPST Analog Switch

The Maxim Integrated MAX4625EZT is a high-performance, single-pole single-throw (SPST) analog switch that operates from a single +1.8V to +5.5V supply. Designed with precision and reliability in mind, this analog switch is an ideal component for a wide range of applications, including battery-powered devices, sample-and-hold circuits, and communication systems.

The MAX4625EZT features low on-resistance (R<sub>ON) of just 1.25Ω (max) at a +5V supply, which remains flat over the specified signal range. This characteristic ensures minimal signal distortion and makes the switch well-suited for passing analog signals. Additionally, the R<sub>ON matching between channels is less than 0.5Ω, and the R<sub>ON flatness is less than 0.5Ω, which further contributes to the switch's excellent performance.

With a low supply current of only 1µA (max) and a low leakage current of 1nA (max) at +25°C, the MAX4625EZT is optimized for power-sensitive applications. The device's TTL/CMOS-logic-compatible control inputs make it easy to interface with a variety of microcontrollers and logic circuits, providing designers with flexibility in system integration.

The MAX4625EZT comes in a compact SOT-23 package, making it an excellent choice for space-constrained applications. Its extended temperature range of -40°C to +85°C ensures reliable operation across various environmental conditions.
