MAX4697：35Ω, Low-Voltage, SPST/SPDT Analog Switches in UCSP Package

The MAX4696/MAX4697/MAX4698 low on-resistance (RON), low-voltage analog switches operate from a single +2.0V to +5.5V supply. The MAX4696/MAX4697 are single-pole/single-throw (SPST) analog switches, and the MAX4698 is a single-pole/double-throw (SPDT) analog switch. The MAX4696 is a normally open (NO) switch, and the MAX4697 is a normally closed (NC) switch. When powered from a 2.7V supply, these devices feature 35Ω (max) RON, with 2Ω (max) RON matching and 13Ω (max) flatness. The MAX4696/MAX4697/MAX4698 offer fast switching speeds (tON = 80ns max, tOFF = 25ns max). The MAX4698 offers a break-before-make function. The digital logic inputs are 1.8V logic compatible from a +2.7V to +3.3V supply and are TTL/CMOS compatible from a +4.5V to +5.5V supply. The MAX4696/MAX4697/ MAX4698 are packaged in the chip-scale package (UCSP™), significantly reducing the required PC board area. The device occupies only a 1.50mm x 1.02mm area. The 3 x 2 array of solder bumps are spaced with a 0.5mm bump pitch.
