LN3005
Ultra Low On-Resistance
■
General Description
The LN3005 is a dual, low on-resistance, low voltage,
bidirectional,
single-pole/double-throw
(SPDT)
CMOS
Low Voltage
Dual SPDT Analog Switch
Laptops, notebooks, palmtops
Communication systems
Sample-and-hold Circuits
Audio signal routing
Audio and video switching
Portable test and measurement
Medical equipment
analog switches designed to operate from a single +1.8V to
+5.5V supply. Targeted applications include battery
powered equipment that benefit from low R
ON
(0.5 Ω) and
fast switching speeds (t
ON
= 16 ns, t
OFF
= 15 ns). The on
resistance profile is very flat over the full analog signal
range. This ensures excellent linearity and low distortion
when switching audio signals.
The LN3005 is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally close (NC) switches. This configuration can be
used as a dual 2-to-1 multiplexer.
