DATASHEET ISL54062 FN6581 Rev 1.00 Negative Signal Swing, Sub-ohm, Dual SPDT with Click and Pop Elimination Nov 3, 2009 Single Supply Switch The Intersil ISL54062 device is a low ON-resistance, low Features voltage, bidirectional, dual single-pole/double-throw (SPDT) Pb-free (RoHS Compliant) 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 Negative Signal Swing (Max 6.5V Below V+) the positive supply rail. Targeted applications include battery Audio Click and Pop Elimination Circuitry powered equipment that benefit from low r (0.56 low ON ON-Resistance (r ) power consumption (20nA) and fast switching speeds ON (t = 55ns, t = 18ns). The digital inputs are 1.8V - V+ = +4.5V 0.55 ON OFF logic-compatible up to a +3V supply. The ISL54062 also - V+ = +4.3V 0.57 features integrated circuitry to eliminate click and pop noise to - V+ = +2.7V 0.82 an audio speaker. The ISL54062 is offered in a small form - V+ = +1.8V . 1.8 factor package, alleviating board space limitations. It is r Matching Between Channels .10m ON available in a tiny 10 Ld 1.8x1.4mm TQFN or 10 Ld 3x3mm TDFN package. r Flatness Across Signal Range 0.35 ON The ISL54062 is a committed dual single-pole/double-throw Low THD+N 32Load 0.02% (SPDT) that consist of two normally open (NO) and two Single Supply Operation . +1.8V to +6.5V normally closed (NC) switches with independent logic control.
