NLAS4684 Ultra-Low Resistance Dual SPDT Analog Switch
The NLAS4684 is an advanced CMOS analog switch fabricated in Sub-micron silicon gate CMOS technology. The device is a dual Independent Single Pole Double Throw (SPDT) switch featuring Ultra-Low RON of 0.5 W, for the Normally Closed (NC) switch, and 0.8 W for the Normally Opened switch (NO) at 2.7 V. The part also features guaranteed Break Before Make switching, assuring the switches never short the driver. The NLAS4684 is available in a 2.0 x 1.5 mm bumped die array. The pitch of the solder bumps is 0.5 mm for easy handling.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. Defined as 10% ON, 90% off duty cycle.

Channel switch control/s test socket is normalized. Off isolation is measured across an off channel. On loss is the bandwidth of an On switch. VISO, Bandwidth and VONL are independent of the input signal direction. VISO = Off Channel Isolation = 20 Log VONL = On Channel Loss = 20 Log VOUT VIN for VIN at 100 kHz
