MAX4591CUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4591CUE is a quad single-pole/single-throw (SPST) analog switch featuring four normally closed channels. It operates on a single +12V or +15V supply with an analog signal range from V- to V+. Electrical specifications include a maximum on-resistance of 16Ω at +15V and 20Ω at +12V, with channel-to-channel matching of 1Ω max and flatness of 1.75Ω max over the signal range. Switching times are tON ≤ 80ns and tOFF ≤ 45ns. The device offers low leakage current (100pA max), charge injection of 5pC max, and ESD protection exceeding 2000V per Method 3015.7. It is housed in a 16-TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required temperature range and package type. Check for RoHS compliance status as older Maxim Integrated products may not meet current environmental standards. Ensure proper handling procedures are followed due to the CMOS construction and sensitivity to static discharge during installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-speed switching of normally closed signals is required under single-supply conditions. The MAX4591CUE is suitable for applications demanding low on-resistance variation across the signal range. Consider the MAX4592CUE if normally open switches are needed instead. Verify that the operating voltage aligns with the +12V or +15V single-supply design constraints specified in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4591CUE belongs to the MAX4591/MAX4592/MAX4593 family of high-speed, precision analog switches manufactured by Analog Devices Inc./Maxim Integrated. These devices are designed for single-supply operation and offer pin compatibility with DG611/DG612/DG613 and DG211/DG212/DG213 series switches. The 'C' suffix indicates a commercial temperature range of 0°C to +70°C, while 'UE' denotes the 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include DG611, DG612, DG613, DG211, DG212, and DG213. Verify electrical parameters such as on-resistance and switching speed against original requirements before substitution.
