The DG2531/DG2532 is a sub 1-W (0.4 W @ 2.7 V ) dual SPDT
analog switches designed for low voltage applications.
condition, all switching elements conduct equally in both
directions. Off-isolation and crosstalk is −69 dB @ 100 kHz.
The DG2531/DG2532 has on-resistance matching (less than
0.05 W @ 2.7 V) and flatness (less than 0.2 W @ 2.7 V) that are
guaranteed over the entire voltage range. Additionally, low
logic thresholds makes the DG2531/DG2532 an ideal
interface to low voltage DSP control signals.
The DG2531/DG2532 has fast switching speed (on/off time @
40 and 35 ns) with break-before-make guaranteed. In the On
The DG2531/DG2532 is built on Vishay Siliconix’s
high-density low voltage CMOS process. An eptiaxial layer is
built in to prevent latchup. The DG2531/DG2532 contains the
additional benefit of 2,000 V ESD protection.
Packaged in space saving MSOP-10, the DG2531/DG2532 is
a high performance, low rON switches for battery powered
applications.
