MAX4684ETB+T Analog Switch ICs 0.5Ohm/0.8Ohm Low-Voltage, Dual SPDT Analog Switches in UCSP

MAX4684ETB+T Datasheet
Product Details

General Description

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.
