Monolithic quad SPST analog switches in the industry's smallest package

Vishay's DG2501, DG2502, and DG2503 analog switches are now available from Digi-Key. They are 200ohm, precision monolithic quad, single-pole single-throw (SPST) devices in the ultra-compact, WCSP, 4 bump by 4 bump array package. The three smallest devices in the industry save space in wearable electronics, sensors, consumer, and communication devices while offering high precision characterized by low parasitic capacitance, charge injection, and leakage current, says the company. Measuring just 1.4mm x 1.4mm with a 0.35mm pitch and top-side lamination for increased ruggedness, the switches are 50 percent smaller than the closest competing device and 95 percent smaller than switches in the standard QFN16 package. Combining their compact size with typical power consumption of less than 0.01µW to prolong battery life, the DG2501, DG2502, and DG2503 are ideal for analog front-end signal switching, programmable gain control, 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).
