Quad SPST switch for precision analog signal routing
The Maxim Integrated MAX4066ACSD+ is a quad single-pole single-throw normally-open analog switch in a 14-SOIC package. Each of the four independent switches presents a maximum 45 Ohm on-resistance with 500 mOhm channel-to-channel matching, making it suitable for audio crosspoint switching, data acquisition front-ends, and sample-and-hold circuits where DC offset from switch resistance must stay below a few millivolts into a high-impedance load. The 100MHz -3dB bandwidth and -86dB crosstalk at 1MHz keep the part viable for composite video switching or multiplexing moderate-speed analog signals up to several megahertz without introducing visible channel bleed. Charge injection of 1pC and off-leakage of 100pA maximum preserve the held voltage in sample-and-hold or integrator reset applications — the 1pC glitch translates to roughly 1mV of offset into a 1nF hold capacitor.
Supply range and temperature grade — fit to the environment
Single-supply operation from 2V to 16V covers common rails. The 0°C to 70°C commercial temperature grade limits deployment to indoor, conditioned environments.
Switching speed and throughput
Maximum turn-on time of 100ns and turn-off time of 75ns set the switching ceiling.
Lifecycle and sourcing
The MAX4066ACSD+ carries an Active lifecycle status with ROHS3 compliance.
