ISL54065EVAL1Z

Dual SPDT with Click and Pop Elimination Single Supply Switch Evaluation Board

概要

The ISL54065EVAL1Z evaluation board is designed to provide a quick and easy method for evaluating the ISL54065 low ON-resistance, low voltage, bidirectional, dual single-pole/double-throw (SPDT) analog switch.

The ISL54065 IC is a single supply SPDT analog switch with negative swing capability, sub-Ω ON-resistance and low power dissipation. The ISL54065 is designed for applications that require an analog switch that may see voltages below ground at the switch terminals, such as audio and video. The ISL54065EVAL1Z evaluation board, developed to evaluate the ISL54065 IC, integrates many features for ease of use in examining the performance of the device under various operating conditions. To help understand the operation of the ISL54065 IC and the ISL54065EVAL1Z evaluation board, refer to the evaluation board schematic and the ISL54065 datasheet.

The ISL54065 IC is a dual SPDT analog switch that 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 ISL54065 also integrates click and pop elimination circuitry to remove transient noises at the speaker during power ON/OFF of an audio system. 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. The evaluation board has selectable output loads of 20kΩ and 32Ω resistors to simulate an audio amplifier pre-amp or stereo headphones. The board also has DC blocking capacitors at the switch input to remove the DC bias of single supply amplifiers.
