Product details

Dual SPST analog switch in 8-SOIC — what the specs mean for your signal path

The Maxim MAX325ESA+ is a dual SPST analog switch with independently controlled normally-open and normally-closed channels, packaged in an 8-SOIC. Each switch presents a maximum on-resistance of 60 ohms, with channel-to-channel matching held to 800 milliohms. Switching speed is 150 ns turn-on, 100 ns turn-off — fast enough for 1 MHz analog multiplexing or audio muting without audible pop. Off-leakage is a maximum 100 pA, and charge injection is 1 pC, both specs that keep the switch from corrupting a sample-and-hold or precision integrator. Crosstalk is rated at -85 dB at 1 MHz, which means the two channels stay isolated well enough for stereo audio or dual-channel data acquisition without bleed-through.

The MAX325ESA+ comes in an 8-SOIC package (3.90 mm body width, 0.154" pitch) and is specified for surface-mount assembly.

Frequently asked questions

What is the closest pin-compatible alternative to MAX325ESA+?

This part is a Maxim-specific dual SPST switch in the SOIC-8 footprint. For a direct pin-compatible alternative, look at the Maxim MAX325CSA+ (same function, commercial temperature range) or the MAX4525CSA+ (similar specs, different switch logic). Verify the switch configuration (NO/NC) and temperature grade against your BOM before substituting.
