Low Voltage, Fault Protection, SP3T Analog Switch
(3:1 Multiplexer/Demultiplexer)
DESCRIPTION
The DG2522 is a low on-resistance SP3T analog switch
design to operation from 1.6 V to 5.5 V.
The DG2522 switches signals in either direction with
amplitudes up to V+. Protection circuit is built in to isolate the
signals if any of them swings above V+. It guaranteed low
leakage level for isolation in power down mode.
Built on Vishay Siliconix’s sub-micro CMOS technology, the
DG2522 achieves switch on-resistance of 0.8
Ω at 4.5 V V+
with 0.6
Ω flatness. It has superior 0.008 % THD (total
harmonic distortion) over frequency of 20 Hz to 20 kHz. It
provides - 59 dB off-Isolation, - 65 dB crosstalk at 1 MHz, and
105 MHz - 3 dB bandwidth.
The select pin of the control logic input can tolerate voltages
above V+ up to 5.5 V. Logic high 1.8 V is guaranteed over the
full V+ range that makes it compatible with many low voltage
digital control circuits.
The features of ultra small package size, wide V+ range, low
on-resistance, low logic threshold, and switch isolation under
fault condition make it an ideal device for battery operated
devices to handle signals such as audio, video, data stream,
and other high accuracy signals.
The DG2522 comes in a small miniQFN-8 lead package of
1.4 mm x 1.4 mm x 0.55 mm. As a committed partner to the
community
and
the
environment,
Vishay
Siliconix
manufactures this product with the lead (Pb)-free device
termination and is 100 % RoHS compliant.
