Vishay – DG2501, DG2502, and DG2503 Monolithic Quad SPST Analog Switches Bring High Precision to Industry’s Smallest Package
Vishay Siliconix DG2501, DG2502, and DG2503 save space in wearable electronics and sensors, and portable healthcare, consumer, industrial, and communication devices, while offering high precision characterized by low parasitic capacitance, charge injection, and leakage current. They are 50 % smaller than the closest competing device and 95 % smaller than switches in the standard QFN16 package.
Product Benefits:
- Ultra-compact WCSP 4 bump by 4 bump array package saves space
- Measures 1.4 mm by 1.4 mm with a 0.35 mm pitch
- Top-side lamination for increased ruggedness
- Low power consumption of < 0.01 μW
- Low drain OFF capacitance of 2.6 pF and drain ON capacitance of 7.6 pF
- Low charge injection down to -0.7 pC
- Low switch-on leakage current of 9 pA
- High ESD tolerance > 8 kV (human body model)
- Latch up current > 800 mA per JESD78
- Four independently selectable SPST switches with closely matched channel resistance
- 1.4 V and 1.8 V logic thresholds ensure low-voltage TTL/CMOS compatibility
- Vishay green, RoHS-compliant, and halogen-free
Market Applications:
Analog front-end signal switching, programmable gain control and sample and hold circuits, and multiple analog input multiplexing in smart watches, medical patches, fitness monitors, sensors, and other such products that make up the Internet of Things (IoT)
