DG412：改进的四路、SPST模拟开关

Maxim's redesigned DG411/DG412/DG413 analog switches now feature low on-resistance matching between switches (3Ω max) and guaranteed on-resistance flatness over the signal range (Δ4Ω max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection, low power consumption, and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers lower off-leakage current over temperature (less than 5nA at +85°C). The DG411/DG412/DG413 are quad, single-pole/single-throw (SPST) analog switches. The DG411 is normally closed (NC), and the DG412 is normally open (NO). The DG413 has two NC switches and two NO switches. Switching times are less than 150ns max for tON and less than 100ns max for tOFF. These devices operate from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim's improved DG411/DG412/DG413 are fabricated with a 44V silicon-gate process.
