MAX4537ESE+ is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC SW SPST-NCX4 100OHM 16SOIC. Review the specifications below when checking this part for your BOM.
The MAX4537ESE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch with a common enable pin. It features four normally closed (NC) switches and operates from +2V to +12V single supplies or ±2V to ±6V dual supplies. The device has an on-resistance of 200Ω maximum, matched between channels to 4Ω maximum, with flatness of 10Ω maximum over the signal range. Turn-on time is 100ns maximum and turn-off time is 80ns maximum at ±4.5V supply. Off-leakage current is 1nA at +25°C and 10nA at +85°C. It is housed in a 16-pin Narrow SO package.
Verify the specific suffix 'E' indicates the industrial temperature range (-40°C to +85°C) and 'SE' denotes the 16-pin Narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the component matches the exact part number to guarantee correct switch configuration and electrical characteristics.
Select this component when a normally closed SPST configuration is required. Verify that the 200Ω on-resistance meets system requirements compared to lower resistance alternatives. Ensure the operating voltage range aligns with the available power supply rails. Consider the 16-pin Narrow SO package dimensions for PCB layout constraints.
This component belongs to the MAX4536/MAX4537/MAX4538 family of quad low-voltage analog switches. The MAX4537 variant specifically provides four normally closed switches, distinguishing it from the MAX4536 (normally open) and MAX4538 (mixed NO/NC). All variants share identical pinouts and electrical specifications except for the switch state logic.
The MAX4536ESE+ and MAX4538ESE+ are pin-compatible within the same series but offer different switch configurations (NO and mixed, respectively). Direct functional replacement requires matching the normally closed requirement.
