MAX4690CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4690CPE+ is a dual SPST CMOS analog switch in a 16-pin Plastic DIP package. It features a maximum on-resistance of 1.25Ω with guaranteed matching of 0.3Ω and flatness of 0.3Ω over the signal range. The device supports +4.5V to +36V single-supply or ±4.5V to ±20V dual-supply operation, with TTL/CMOS-compatible logic inputs. Electrical characteristics include a maximum off-leakage current of 5nA at +85°C, turn-on time of 400ns, and turn-off time of 300ns under dual supply conditions. It provides greater than 2kV ESD protection and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and temperature grade. Check for RoHS compliance status and ensure the part number corresponds to the dual normally open configuration rather than the complementary variants.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are critical for signal integrity. Ensure the application requires two normally open switches, distinguishing it from the MAX4680 (normally closed) and MAX4700 (mixed). Verify that the single or dual supply voltage ranges align with the system power architecture and that the PDIP-16 package fits the board layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4680/MAX4690/MAX4700 family of dual analog switches. While electrically similar regarding resistance and speed, the MAX4690 is distinctively configured with two normally open switches. This contrasts with the MAX4680, which offers two normally closed switches, and the MAX4700, which combines one of each with guaranteed break-before-make timing.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4690 and MAX4680?

The MAX4690 contains two normally open (NO) switches, whereas the MAX4680 contains two normally closed (NC) switches. Both share identical electrical specifications for on-resistance and leakage.

Does the MAX4690 support break-before-make switching?

No, guaranteed break-before-make switching is a feature specific to the MAX4700 variant. The MAX4690 consists of independent normally open switches without this specific timing guarantee.

How does the logic supply pin affect operation?

The separate VL pin ensures TTL/CMOS logic compatibility regardless of the analog supply voltage range, allowing the device to operate correctly from +4.5V to +36V single supply or ±4.5V to ±20V dual supplies.
