DG2531/DG2532 Vishay Siliconix 0.4-Ω Low-Voltage Dual SPDT Analog Switch DESCRIPTION FEATURES The DG2531/DG2532 is a sub 1-Ω (0.4 Ω at 2.7 V) dual SPDT analog switches designed for low voltage applications. • • • • • The DG2531/DG2532 has on-resistance matching (less than 0.05 Ω at 2.7 V) and flatness (less than 0.2 Ω 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. Low Voltage Operation (1.8 V to 5.5 V) Low On-Resistance - rON: 0.4 Ω at 2.7 V - 69 dB OIRR at 2.7 V, 100 kHz MSOP-10 Package ESD Protection > 2000 V RoHS COMPLIANT BENEFITS • Reduced Power Consumption 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. • High Accuracy • Reduce Board Space • 1.6 V Logic Compatible • High Bandwidth APPLICATIONS • Cellular Phones • Speaker Headset Switching • Audio and Video Signal Routing • PCMCIA Cards • Battery Operated Systems • Relay Replacement FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG2531 MSOP-10 V+ 1 10 NO2 NO1 2 9 COM2 COM1 3 8 IN2 IN1 4 7 NC2 6 GND NC1 5 Top View TRUTH TABLE Logic NC1 and NC2 NO1 and NO2 0 ON OFF 1 OFF ON DG2532 MSOP-10 V+ 1 10 NC2 NC1 2 9 COM2 COM1 3 8 IN2 IN1 4 7 NO2 NO1 5 6 GND Top View Document Number: 72742 S-71009–Rev.
