Descriptions
The DIO1520 is a dual Single-Pole, Double-Throw
(SPDT) analog switch. The DIO1520 operates
from a single 1.65 V to 5.85 V supply and features
an ultra-low on resistance of 0.7 Ω at a 3 V supply
and TA = 25°C. This device is fabricated with
sub-micron CMOS technology to achieve fast
switching speed and is designed for
break-before-make operation.
The DIO1520 guarantees 0.02 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. The DIO1520 consists of two normally
open and two normally close switches.
The DIO1520 provides the Green package with
10-lead QFN.
