MAX4522CUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4522CUE+ 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 capable of handling rail-to-rail analog signals. The device operates with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 100Ω, an off-leakage current of 1nA at +25°C, and TTL/CMOS-compatible digital inputs. The component is housed in a 16-TSSOP package and is specified for operation within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature rating. Ensure that the requested part number matches the required logic configuration, as the MAX4522 family includes variants with different switch states. Cross-reference the datasheet revision history to confirm the availability of the TSSOP package variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low-voltage SPST switching with rail-to-rail signal capability. Verify that the system's logic levels are compatible with the device's input thresholds, particularly at higher supply voltages where the threshold may exceed standard TTL high-level minimums. Consider the thermal derating requirements if operating near the upper limits of the specified temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4522CUE+ belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage analog switches. While the MAX4521 contains normally closed switches and the MAX4523 offers a mix of both, the MAX4522 specifically provides four normally open switches. This family shares identical pinouts and electrical characteristics, differing primarily in the default state of the internal CMOS switches.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4522 differ from the MAX4521?

The MAX4522 contains four normally open (NO) switches, whereas the MAX4521 contains four normally closed (NC) switches. Both share the same package, pinout, and electrical specifications.

What happens if an analog signal exceeds the supply voltage?

Internal reverse ESD-protection diodes connect each analog-signal pin to V+ and V-. If a signal exceeds these rails, one of these diodes conducts, clamping the voltage.

Is the MAX4522 compatible with TTL logic at +5V?

Yes, when using a +5V supply, the digital inputs have +0.8V and +2.4V logic thresholds, ensuring compatibility with TTL and CMOS logic levels.
