Crosstalk between channels is rated at -92 dB at 100 kHz, which keeps leakage of an active signal into an off channel well below the noise floor of a 16-bit ADC system — a key parameter for precision multiplexing. Charge injection is 2 pC typical, so the voltage glitch on the analog bus when switching channels stays small — important for sample-and-hold circuits or when driving a high-impedance load that cannot absorb the injected charge quickly.","metaTitle":"MAX309ESE+ Analog Devices SP4T Analog Switch, 2-Circuit","metaDescription":"MAX309ESE+ from Analog Devices: dual 4:1 multiplexer/SP4T switch, 100Ohm on-resistance, 150ns switching, -92dB crosstalk, 16-SOIC.
