This topology is suited for routing analog or digital signals where each channel needs independent on/off control without cross-connection. Each switch presents a maximum on-resistance of 45 Ohms, with channel-to-channel matching held to 500 mOhm max — a figure that matters in gain-setting or differential signal paths where resistance mismatch introduces offset error. ## Bandwidth and isolation for mixed-signal boards The -3 dB bandwidth extends to 100 MHz, and crosstalk between channels is specified at -86 dB at 1 MHz. Together these ratings mean the switch passes a 10 MHz analog signal with under 0.1 dB of attenuation while keeping feedthrough from an adjacent channel more than 80 dB down — relevant for multiplexing video, IF, or high-speed data lines on the same IC. Switching times are 100 ns max for turn-on (Ton) and 75 ns max for turn-off (Toff), which sets the channel update rate ceiling. For a system scanning four sensor inputs, the aggregate throughput is limited by the sum of Ton plus the settling time of the downstream ADC input stage. ## Charge injection and leakage in precision paths Charge injection is rated at 1 pC typical — the amount of charge dumped onto the signal node when the switch opens. In a sample-and-hold front end driving a 16-bit ADC with a 10 nF hold capacitor, 1 pC produces a 100 µV step, which is below the 1 LSB threshold for a 5 V reference. Off-channel leakage is 1 nA max, and each channel presents 9 pF of capacitance to ground in both the on and off states. ## Package, temperature grade, and compliance Analog Devices lists this part as Active in production and ROHS3 compliant.","metaTitle":"MAX4066CSD+T Analog Devices SPST Switch, 45Ohm, 14-SOIC","metaDescription":"MAX4066CSD+T quad SPST-NO analog switch, 45Ohm on-resistance, 100MHz bandwidth, -86dB crosstalk.
