MAX4512CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4512CSE+ is a quad, single-pole/single-throw (SPST), fault-protected analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four separately controlled switches with normally open terminals protected from overvoltage faults up to 36V during power-up or power-down. The device operates with dual power supplies ranging from ±4.5V to ±18V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 175 Ω matched to 10 Ω max between channels, off-leakage current of 0.5nA at +25°C, and logic thresholds compatible with TTL and CMOS. It is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection on NO_ and NC_ terminals allows signals within or slightly beyond supply rails to pass through while clamping the COM_ output during overvoltage conditions.
• Rail-to-Rail signal handling capability ensures unambiguous outputs during fault transitions without transition glitches.
• Pin-compatible with industry-standard non-protected switches such as DG201/DG202/DG213 and DG411/DG412/DG413.

Analog Switches, Multiplexers, Demultiplexers Applications

• ATE Equipment
• Data Acquisition Systems
• Industrial and Process-Control Systems
• Avionics
• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature range and package type. The 'C' designation indicates a commercial temperature range of 0°C to +70°C. Ensure the narrow SOIC package dimensions match the target PCB footprint. Confirm RoHS compliance status for environmental regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required on the analog signal path without compromising rail-to-rail signal integrity. It serves as a direct replacement for legacy DG201/DG202/DG213 devices where higher voltage tolerance is needed. Consider the 175 Ω on-resistance limit for applications requiring lower signal attenuation.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4512CSE+ belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. While sharing identical pinouts and core architecture, the MAX4512 specifically provides four normally open switches, distinguishing it from the MAX4511 (normally closed) and MAX4513 (mixed configuration).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include MAX4511CSE+ and MAX4513CSE+. These parts share the same pinout and fault-protection architecture but differ in switch configuration (NC vs NO). Verify that the specific switch state matches the circuit design requirements before substitution.
