MAX14777 Quad Beyond-the-Rails™ -15 V to +35 V Analog Switch

Quad SPST Beyond-the-Rails™ switch from Maxim simplifies power supplies

Image of Maxim Integrated's MAX14777 Quad Beyond-the-Rails™ -15 V to +35 V Analog Switch

The MAX14777 quad SPST switch supports analog signals above and below the rails with a single 3.0 V to 5.5 V supply. The device features a selectable -15 V/+35 V or -15 V/+15 V 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 10 Ω (max) on-resistance, and 9 mΩ (typ) RON flatness, along with a low 50 nA (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 60 mA (max) of continuous current in either direction. The MAX14777 is available in a 20-pin (4 mm x 4 mm) TQFN package and is specified over the -40°C to +105°C temperature range.
