Product Details

The MAX14777 quad SPST switch supports analog signals above and below the rails with a single 3.0V to 5.5V supply. The device features a selectable -15V/+35V or -15V/+15V analog signal range for all switches. Each switch has a separate control input to allow independent switching, making the device an alternative to opto-relays in applications that do not need galvanic isolation.
The IC features 10Ω (max) on-resistance, and 9mΩ (typ) RON flatness, along with a low 50nA (max at +85°C) on-leakage. For maximum signal integrity, the device keeps this performance over the entire common-mode voltage range. Each switch can carry up to 60mA (max) of continuous current in either direction.
The MAX14777 is available in a 20-pin (4mm x 4mm) TQFN package and is specified over the -40°C to +105°C temperature range.
