Descriptions
The DIO1268 is a dual Single-Pole, Double-Throw
(SPDT) analog switch. DIO1268 operates from a
single 1.6 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 DIO1268 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. The DIO1268 consists of two normally
open and two normally close switches.
The DIO1268 provides packages with Green
QFN1.4*1.8-10, QFN1.5*2.0-10.
