MAX4712CSE Equivalent & Substitute Parts
Part Overview
The MAX4712CSE is a 4-circuit SPST-NO (Single Pole Single Throw - Normally Open) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 25Ohm on-state resistance and is housed in a 16-SOIC surface mount package. The MAX4712CSE is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, design updates, and procurement planning.

Substitute Part Grouping Explanation
Substitution of the MAX4712CSE is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for switch circuit topology (SPST-NO), circuit count (4), multiplexer configuration (1:1), on-state resistance (25Ohm), supply voltage ranges (2.7V ~ 11V single, ±2.7V ~ 5.5V dual), switching times (125ns/80ns), charge injection (25pC), channel capacitance (8pF/8pF), leakage current (500pA max), crosstalk performance (-87dB @ 1MHz), operating temperature range (0°C ~ 70°C), and package format (16-SOIC surface mount).
The MAX4712CSE+ qualifies as a parametric equivalent substitute based on complete electrical and mechanical parameter alignment with the original part.
