Sub-Ω, Low Voltage, SPDT Analog Switches with Over Current Protection

Transcription

1 New Product DG/DG1 Sub-Ω, Low Voltage, SPDT Analog Switches with Over Current Protection DESCRIPTION The DG/DG1 are low-voltage single single-pole/ double-throw monolithic CMOS analog switches. Designed to operate from 1.8 V to. V power supply, the DG/ DG1 provide low on-resistance (.8 Ω), excellent onresistance matching (.6 Ω) and flatness (. Ω) over the entire signal range. The DG/DG1 offers the advantage of high linearity that reduces signal distortion, making ideal for audio, video, and USB signal routing applications. Additionally, the DG/DG1 are 1.6 V logic compatible within the full operation voltage range. The DG/DG1 offer over current protection. The protection circuitry activates when voltage drop across switch reaches.6 V typical. A direct/sustained short circuit will cause the switch to pulse on for typically less than 1 µs, then turn off. The switch turns on after ms. If the short circuit condition remains, the switch turns off and on to produce a pulsed output. The current limiting circuitry is not instantaneous, and therefore will not activate when the output charges a small.1 µf capacitor. Built on s proprietary sub-micron high-density process, the DG/DG1 brings low power consumption at the same time as reduces PCB spacing with the TSOP6 package As a committed partner to the community and the environment, manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured with 1 % matte tin device termination, the lead (Pb)-free - E3 suffix is being used as a designator.
