Rev 1.00
Nov 3, 2009 Negative Signal Swing, Sub-ohm, Dual SPDT with Click and Pop Elimination
Single Supply Switch
The Intersil ISL54062 device is a low ON-resistance, low
voltage, bidirectional, dual single-pole/double-throw (SPDT)
analog switch. It is designed to operate from a single +1.8V to
+6.5V supply and pass signals that swing down to 6.5V below
the positive supply rail. Targeted applications include battery
powered equipment that benefit from low rON (0.56пЃ—пЂ©пЂ¬пЂ low
power consumption (20nA) and fast switching speeds
(tON = 55ns, tOFF = 18ns). The digital inputs are 1.8V
logic-compatible up to a +3V supply. The ISL54062 also
features integrated circuitry to eliminate click and pop noise to
an audio speaker. The ISL54062 is offered in a small form
factor package, alleviating board space limitations. It is
available in a tiny 10 Ld 1.8x1.4mm ВµTQFN or 10 Ld 3x3mm
TDFN package.
The ISL54062 is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally closed (NC) switches with independent logic control.
This configuration can be used as a dual 2-to-1 multiplexer.
