Each switch presents a maximum on-resistance of 60 Ohm, with channel-to-channel matching held to 800 mOhm — the resistance mismatch between the two channels stays under one ohm, which matters when the switch pair carries a differential signal where gain symmetry is required. ## Supply range and signal handling The 1:1 multiplexer/demultiplexer circuit means each switch is a straight pass-gate — no internal routing logic, just the FET channel between the source and drain terminals. Switching times are 150 ns max for turn-on (Ton) and 100 ns max for turn-off (Toff). In a multiplexed data-acquisition front-end sampling at 500 kSPS, the 150 ns settling window after the switch closes must be budgeted before the ADC conversion starts — the switch itself does not limit the throughput, but the downstream settling does. Charge injection is 1 pC typical. When the switch opens, this charge packet couples onto the hold capacitor of a downstream sample-and-hold — 1 pC into a 10 pF cap produces a 100 mV glitch, so the cap value and the acquisition time after the switch opens must be sized to absorb the injected charge before the ADC samples. ## Crosstalk and leakage in precision analog paths Crosstalk between channels is rated at -85 dB at 1 MHz. In a dual-channel multiplexer switching audio or low-frequency sensor signals, this isolation means the closed channel sees less than 0.006 % of the signal from the open channel at 1 MHz — the coupling capacitance through the substrate and package is the dominant path, and the -85 dB figure confirms the die layout and pinout keep the channels electrically separate. Off-state leakage current is 100 pA maximum. In a high-impedance node such as a photodiode amplifier input, 100 pA of leakage from the open switch adds to the sensor's dark current — for a 10 pA photodiode, the switch leakage doubles the baseline offset and must be calibrated out or trimmed at the system level. Channel capacitance is 9 pF for both the source and drain terminals when the switch is off. This capacitance loads the signal line and sets the bandwidth of the off-channel — a 9 pF cap in parallel with a 10 kOhm source impedance creates a 1.8 MHz low-pass pole, which is acceptable for most audio and instrumentation signals but limits RF or video paths. ## Package, temperature grade, and compliance The supplier device package is 8-SOIC, surface-mount, with a tube shipping medium.","metaTitle":"MAX323ESA+ Analog Devices SPST Switch, 60Ohm, 8-SOIC","metaDescription":"MAX323ESA+ dual SPST analog switch, 60Ohm on-resistance, 150ns switching, -85dB crosstalk.

In a precision analog multiplexer, the on-resistance adds to the source impedance and creates a voltage divider with the load — the 60 Ohm figure means the switch contributes less than 0.6 % error into a 10 kOhm load. The matching figure ensures both channels present nearly identical resistance, preserving differential gain symmetry."},{"question":"What compliance documentation does Analog Devices provide for MAX323ESA+?","answer":"The MAX323ESA+ is ROHS3 compliant per the manufacturer's declaration.
