MAX4522EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4522EPE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally open switches housed in a 16-pin Plastic DIP package with an operating temperature range of -40°C to +85°C. The device supports dual power supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 100Ω, an on-resistance match between channels of 10Ω max, and an on-resistance flatness of 12Ω max. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C. Supply currents are typically 0.05µA, and the device offers 2kV ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required temperature grade and package type. Ensure that the procurement documentation aligns with the latest datasheet revisions to guarantee functional compatibility and reliability standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4522EPE+ when four normally open analog switches are required within a low-voltage system. This part is appropriate for applications demanding rail-to-rail signal transmission and TTL/CMOS logic compatibility. Consider the ±2V to ±6V dual supply or +2V to +12V single supply constraints during circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage, SPST analog switches. While sharing similar electrical characteristics and pinouts, the MAX4522EPE+ is distinguished by its configuration of four normally open switches, whereas the MAX4521 offers four normally closed switches and the MAX4523 provides a mixed configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX4521EPE+ and MAX4523EPE+. These parts share identical pinouts and electrical specifications but differ in switch state configuration. Verify that the alternative switch logic (normally open vs. normally closed) meets the circuit requirements before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4522 and MAX4521?

The primary difference lies in the switch configuration. The MAX4522 contains four normally open (NO) switches, while the MAX4521 contains four normally closed (NC) switches. Both share the same package, pinout, and electrical performance characteristics.

Can the MAX4522EPE+ operate with a single supply voltage?

Yes, the device can operate with a single supply voltage ranging from +2V to +12V. In this configuration, the V- pin is connected to ground (GND).

How does the on-resistance vary with the analog signal voltage?

The on-resistance is designed to be flat over the specified signal range, with a maximum variation (flatness) of 12Ω. This ensures consistent signal transmission regardless of the analog voltage level within the supply limits.
