Maxim's redesigned DG412 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 DG412 are quad, single-pole/single-throw (SPST) analog switches. The DG412 is normally open (NO). Switching times are less than 150ns max for t_ON and less than 100ns max for t_OFF. These devices operate from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. Maxim's improved DG412 are fabricated with a 44V silicon-gate process.
