ISL54062

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

power consumption (20nA) and fast switching speeds

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 µTQFN 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.
