Descriptions
The DIO1523 is a dual single-pole, double-throw
(SPDT) analog switch. DIO1523 operates from a
single 1.8 V to 4.2 V supply and features an
ultra-low on resistance of 0.75 Ω at a 4.2 V supply
and TA = 25°C. This device is fabricated with
sub-micron CMOS technology to achieve fast
switching speeds and is designed for
break-before-make operation.
The DIO1523 guarantees 0.03 Ω on-resistance
matching between switches, on-resistance
flatness over the signal range, high off-isolation
and low crosstalk, which ensures excellent
linearity and low distortion when switching audio
signals. DIO1523 consists of two normally open
and two normally close switches.
