Quad, SPST, CMOS Analog Switches
MAX4604/MAX4605/MAX4606 quad analog switches feature on-resistance. On-resistance matched between switches flat (0.5 max) over specified signal range. Each switch handle Rail-to-Rail® analog signals. off-leakage current only 2.5nA +85°C. These analog switches ideal low-distortion applications preferred solution over mechanical relays automatic test equipment applications where current switching required. These switches have power requirements, require less board space, more reliable than mechanical relays. MAX4604 four normally closed (NC) switches, MAX4605 four normally open (NO) switches, MAX4606 switches. These switches operate from single supply +4.5V +36V from dual supplies ±4.5V ±20V. digital inputs have +0.8V +2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using ±15V supplies single +12V supply.

Always sequence first, then followed logic inputs, COM. power-supply sequencing possible, small signal diodes (D1, series with supply pins overvoltage protection (Figure Adding diodes reduces analog signal range diode drop below diode drop above does affect devices' switch resistance leakage characteristics.

Off-Isolation High Frequencies
systems, high-frequency on-response these parts extends from above 100MHz with typical loss -2dB. When switch turned off, however, behaves like capacitor, isolation decreases with increasing frequency. (Above 300MHz, switch actually passes more signal turned than turned on.) This effect more pronounced with higher source load impedances. Above 5MHz, circuit board layout becomes critical, becomes difficult characterize response
