MAXIM MAX4684EUB+

The MAX4684/MAX4685 low on-resistance (Ron), low-voltage, dual single-pole/double-throw (SPDT) analog switches operate from a single +1.8V to +5.5V supply. The MAX4684 features a 0.5Ω (max) Ron for its NC switch and a 0.8Ω (max) Ron for its NO switch at a +2.7V supply. The MAX4685 features a 0.8Ω max on-resistance for both NO and NC switches at a +2.7V supply. Both parts feature break-before-make switching action (2ns) with ton = 50ns and toff = 40ns at +3V. The digital logic inputs are 1.8V logic-compatible with a +2.7V to +3.3V supply. The MAX4684/MAX4685 are packaged in the chipscale package (UCSP), significantly reducing the required PC board area. The chip occupies only a 2.0mm × 1.50mm area. The 4×3 array of solder bumps are spaced with a 0.5mm bump pitch.
