| DG2531/DG2532 New Product Vishay Siliconix 0.4- Low-Voltage Dual SPDT Analog Switch DESCRIPTION The DG2531/DG2532 is a sub 1- (0.4 at 2.7 V) dual SPDT analog switches designed for low voltage applications. The DG2531/DG2532 has on-resistance matching (less than 0.05 at 2.7 V) and flatness (less than 0.2 at 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 at 40 and 35 ns) with break-before-make guaranteed. In the On condition, all switching elements conduct equally in both directions. Off-isolation and crosstalk is - 69 dB at 100 kHz. 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 2000 V ESD protection. Packaged in space saving MSOP-10, the DG2531/DG2532 is a high performance, low rON switches for battery powered applications.
