Negative Signal Swing, Sub-ohm, Dual SPDT, Single Supply Switch Evaluation Board

The ISL54059EVAL1Z evaluation board is designed to provide a quick and easy method for evaluating the ISL54059 analog switch IC.

The ISL54059 IC is a single supply, dual single-pole/double-throw (SPDT) analog switch that features negative swing capability, sub-Ω ON-resistance, and low power dissipation. The IC is designed for applications that require an analog switch that may see voltages below ground at the switch terminals, such as for audio and video. The evaluation board integrates many features for ease of use in examining the performance of the device under various operating conditions.

The analog switch IC is capable of swinging down to 6.5V below the positive supply rail. For example, if the supply is at +1.8V, the switch terminal analog operating range is from -4.3V to +1.8V. The evaluation board contains standard RCA/BNC connectors and a single headphone jack to allow the user to easily interface with the IC to evaluate its functions, features and performance.
