MAX4684-MAX468519-1977; Rev 3; 2/030.5/0.8 Low-Voltage, Dual SPDT Analog Switches in UCSP MAX4684/MAX4685General DescriptionThe MAX4684/MAX4685 low on-resistance (RON), lowvoltage, dual single-pole/double-throw (SPDT) analog switches operate from a single +1.8V to +5.5V supply. The MAX4684 features a 0.5 (max) RON for its NC switch and a 0.8 (max) RON for its NO switch at a +2.7V supply. The MAX4685 features a 0.8 max onresistance 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 ……
