MAX4690EAE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690EAE+T is a dual SPST CMOS analog switch manufactured by Analog Devices Inc. (Maxim Integrated). It features a maximum on-resistance of 1.25Ω with guaranteed matching between channels to 0.3Ω and flatness over the signal range to 0.3Ω. The device supports single-supply operation from +4.5V to +36V or dual supplies from ±4.5V to ±20V, with TTL/CMOS-compatible logic inputs. Electrical characteristics include an off-leakage current of 5nA max at +85°C, turn-on time up to 275ns, and turn-off time up to 175ns under dual supply conditions. It is housed in a 16-lead SSOP package and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• TTL/CMOS-compatible control inputs independent of the analog supply voltage

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Data acquisition systems requiring current switching
• Sample-and-hold circuits
• Communication systems and PBX/PABX applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the ordering suffix matches the specific package type and temperature grade required for your design. Ensure compliance with RoHS directives as indicated by the '+' suffix. Cross-reference the datasheet revision date to confirm the electrical specifications align with your system requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are critical. The MAX4690 provides normally open switches, distinguishing it from the MAX4680 (normally closed) and MAX4700 (mixed configuration). Ensure the application voltage does not exceed the absolute maximum ratings of +44V or -44V relative to ground. Consider the 16-SSOP package constraints for thermal dissipation if operating near the upper limits of the power supply range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. While sharing similar electrical characteristics and pinouts, the MAX4690 specifically offers two normally open switches. This distinguishes it from the MAX4680, which contains two normally closed switches, and the MAX4691, which is a multiplexer variant. The family is designed to replace mechanical relays in space-constrained applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4680EAE+T serves as a functional substitute if normally closed contacts are acceptable. The MAX4700EAE+T is compatible if mixed NO/NC functionality or break-before-make timing is required. For higher channel counts, consider the MAX4603 series. Verify that any replacement maintains the same 16-SSOP footprint and electrical parameters such as on-resistance and leakage current.
