Negative Supply Voltage Output. Connect NEG to GND with a 3.3nF capacitor. Do not use NEG to
power any external circuitry.
Positive Supply Voltage Input. Connect V
with a 0.1µF ceramic capacitor placed as close as possible to the device.
Analog Switch 1, Normally Open Terminal
Analog Switch 2, Common Terminal
Active-Low Enable Input. Drive EN high to put switches in a high-impedance mode. Shunt click/pop
switches are not affected by the state of EN. The MAX14505A/MAX14506 enter a low current state
when EN is driven high.
