MAX325 General Description
The MAX323/MAX324/MAX325 are precision, dual,SPST analog switches. They are single-supply devices designed to operate from +2.7V to +16V. The MAX323 has two normally open (NO) switches, and the MAX324 has two normally closed (NC) switches. The MAX325 has one NO and one NC switch. Low power consumption (5W) makes these parts ideal for battery-powered equipment. These switches offer low leakage currents (100pA max) and fast switching speeds (tON = 150ns max, tOFF = 100ns max).
When powered from a 5V supply, the MAX323 series offers 2 max matching between channels, 60 max on-resistance, and 6 max RON flatness.
