MAX4619EUE Description

The MAX4619EUE is a high-performance, single-pole double-throw (SPDT) analog switch designed by Analog Devices Inc./Maxim Integrated. This device is part of the MAX4619 family and is housed in a 16-TSSOP surface-mount package. It features three independent SPDT switches, each with a on maximum-state resistance (R_on) of 10Ω, ensuring low power consumption and minimal signal attenuation. The MAX4619EUE operates over a wide supply voltage range of 2V to 5.5V, making it suitable for various power supply configurations.

The device boasts a low leakage current (I_S(off)) of 1nA, which is crucial for maintaining signal integrity in low-power applications. Additionally, it offers excellent channel-to-channel matching with a ΔR_on of 200mΩ, ensuring consistent performance across all channels. The MAX4619EUE also features low charge injection (3pC) and low channel capacitance (5pF for CS(off) and 8.5pF for CD(off)), which are critical for high-speed switching applications.

The switch time for the MAX4619EUE is impressively fast, with a maximum turn-on time (T_on) of 15ns and turn-off time (T_off) of 10ns. This rapid switching capability makes it ideal for applications requiring high-frequency signal routing. The device is REACH unaffected and has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited exposure to ambient conditions.
