RS2118 0.8Ω, Low Ron, Dual SPDT Analog Switch with Negative Rail Capability FEATURES • Low ON-State Resistance:0.8Ω (TYP) • Supply Range: +2.5V to +5.5V • Negative Signal Swing Capability: -2V to V+ • Break-Before-Make Switching • • Fast Switching Times 1.8V Logic Control • Rail-to-Rail Input and Output Operation • Extended Industrial Temperature Range: -40°C to +85°C Available in Green QFN-1.4x1.8-10L Package • DESCRIPTION The RS2118 is a bidirectional, 2-channel single-pole double-throw (SPDT) analog switch that is designed to operate from 2.5V to 5.5V. The device features negative signal capability that allows signals below ground to pass through the switch without distortion. The break-before-make feature prevents signal distortion during the transferring of a signal from one path to another. Low ON-state resistance, excellent channel-to-channel ON-state resistance matching, and minimal total harmonic distortion (THD) performance are ideal for audio applications This device is available packaged in QFN-1.4x1.8-10L.

Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3V beyond the supply rails should be current-limited to 10mA or less.

All unused digital inputs of the device must be held at VCC or GND to ensure proper device operation. Tie the digitally controlled inputs select pins IN1 and IN2 to VCC or GND to avoid unwanted switch states that could result if the logic control pins are left floating.
