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.
