MAX4645 - 快速、低电压、2.5Ω、SPST、CMOS模拟开关 - 宽带交换 - Maxim美信半导体高性能芯片品质 - 美信半导体
The MAX4645/MAX4646 single-pole, single-throw (SPST) analog switches feature a 2.5Ω typical on-resistance (RON) from a +5V supply. RON is flat (0.4Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. Off-leakage current is 0.25nA max at +25°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automated test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays.
These switches operate from a +1.8V to +5V single supply, making them ideal for use in battery-powered applications. The MAX4645/MAX4646 have fast switching speeds of 12ns turn-on time (tON) and 8ns turn-off time (tOFF).
The MAX4645 is a normally open (NO) switch, and the MAX4646 is a normally closed (NC) switch. Both are available in 5-pin SOT23, 6-pin SOT23, and 8-pin µMAX® packages.
