MAX4512ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4512ESE+T is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It operates within a temperature range of -40°C to +85°C and utilizes a 16-pin Narrow SO package. The device supports dual power supplies from ±4.5V to ±18V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 175Ω and an on-resistance match between channels of 10Ω max. Off-leakage current is specified at 0.5nA at +25°C and 10nA at +85°C. The switches feature fault protection on NO_ and NC_ terminals up to ±36V with power applied.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs handle overvoltage faults up to 36V during operation and 40V when powered off.
• Rail-to-Rail signal handling capability ensures unambiguous outputs during fault transitions.
• Output clamps to the appropriate supply voltage during fault conditions without generating transition glitches.
• Pin-compatible with industry-standard non-protected switches such as DG201, DG202, and DG213.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact temperature grade and packaging configuration. Ensure that the component source matches the authorized distributor list for Analog Devices Inc. to guarantee authenticity and traceability. Cross-reference the datasheet revision date with the procurement batch to ensure compliance with current manufacturing standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when rail-to-rail signal integrity is required alongside robust fault protection for input terminals. Verify that the application logic thresholds align with TTL or CMOS compatibility requirements under the intended supply voltage. Confirm that the package thermal dissipation characteristics meet the system's power budget constraints during continuous operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. The MAX4512 variant specifically provides four normally open switches, distinguishing it from the MAX4511 which offers normally closed switches and the MAX4513 which combines both types. All variants share identical pinouts and core fault-protection architectures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4512ESE+T is designed as a direct pin-compatible replacement for the DG412, DG202, and DG213. Designers should verify that the existing circuit layout accommodates the specific fault-protection behavior of the NO_ and NC_ pins compared to traditional unprotected switches.
