1 ompact, Low Power onsumption, Triple SPDT (Triple 2: Multiplexers) DG944 DESRIPTION The DG944 is a triple SPDT (triple 2: multiplexers) with enhanced performance on low power consumption, while guarantees.8 logic compatible over the full operation voltage range. The DG944 is designed to operate from a to supply at +, and + 2. to +. at. The DG944 is a high precision switch of low parasitic capacitance, low leakage, low charge injection, and fast switching speed. Processed with advanced MOS technology, the DG944 conducts equally well in both directions, offers rail to rail analog signal handling and can be used both as multiplexers as well as de-multiplexers. The advantages of DG944 at size, weight, power consumption, and low voltage control capability make it ideal for portable consumer applications such as 3D glasses (3D goggles). Its precise switching, wide dynamic range, and low parasitic characters make it a high performance switch for healthcare, data acquisition, and instrument products. The DG944 operating temperature is specified from - 4 to + 8 and are available and the ultra compact.8 mm x 2.6 mm miniqfn6 packages. s a comitted partner to the community and the environment, manufactures this product with lead (Pb)-free device terminations. DG944 is offered in a miniqfn package. The miniqfn package has a nickelpalladium-gold device termination and is represented by the lead (Pb)-free -E4 suffix. The nickel-palladium-gold device terminations meet all JEDE standards for reflow and MSL ratings. FETURES Operates with + = 2.7 to 3.2 ; = 2. to. Guaranteed.8 logic control at full + range Low power consumption, < µ High bandwidth: 4 MHz Low charge injection over the full signal range (less than.9 pq) Low switch capacitance ( s(off) 2 pf typ.)
