Product Description

The 392A is a monolithic analog switches designed for low-voltage, single-supply operation. This high-precision device is ideal for low-distortion audio, video, signal switching and routing applications. The PI5A392A has four normally open (NO) switches. Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails. The 392A is fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <12-ohm on-resistance. On-resistance matching between channels is within 2-ohm. On-resistance flatness is less than 4ohm over the full signal range. The PI5A39X family guarantees fast switching speeds (tON < 20ns). This product is available in the 16-pin QSOP package for operation over the industrial (-40oC to +85 oC) temperature range.
