MAX4852ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4852ETE+ is a dual single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +5.5V supply and supports signals exceeding the positive rail without distortion. The device features two SPDT switches with no internal comparators, resulting in a low supply current of 1µA. It includes a 3.5Ω on-resistance channel and a 7Ω on-resistance channel. Key electrical parameters include a -3dB bandwidth of 135MHz for the 7Ω switch, 100MHz for the 3.5Ω switch, and an off-isolation of -95dB at 1MHz. The package is a 16-pin Thin Quad Flatpack (TQFN) measuring 3mm x 3mm.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports over-rail signal handling where signals up to 5.5V pass through the switch even when the supply voltage is lower than the signal level.
• Provides low on-resistance options with 3.5Ω and 7Ω channels to minimize signal attenuation.
• Features ultra-low supply current consumption of 1µA due to the absence of integrated comparators.
• Compatible with 1.8V logic levels while accepting digital control inputs up to 5.5V.

Analog Switches, Multiplexers, Demultiplexers Applications

• USB switching for full-speed data signals
• Audio-signal routing in portable devices
• Cellular phones and notebook computers

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component matches the exact suffix ETE+, which indicates the specific temperature range and package variant. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure authenticity. Check the exposed paddle connection requirements during assembly to maintain proper grounding and thermal performance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual SPDT configuration is required without the need for headphone detection comparators found in the MAX4850 family. Ensure the application requires the specific 3.5Ω/7Ω resistance split. Verify that the system logic levels are compatible with the specified input thresholds across the operating voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4850/MAX4852H family of dual SPDT analog switches. Unlike the MAX4850 variants, the MAX4852 series omits internal comparators to achieve lower power consumption. It shares the same 16-pin TQFN footprint and over-rail signal capabilities as its sibling parts within the datasheet.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4852 handle signals that exceed the VCC supply voltage?

The MAX4852 allows signals up to 5.5V to pass through the switch without distortion, even if the positive supply rail is exceeded.

What is the difference between the 3.5Ω and 7Ω channels in this device?

The device contains two independent SPDT switches; one has a typical on-resistance of 3.5Ω and the other has a typical on-resistance of 7Ω.

Does the MAX4852ETE+ include internal comparators?

No, the MAX4852 family does not include internal comparators, unlike the MAX4850 family, which results in a lower supply current of 1µA.
