PI5A391A PI5A392A PI5A393A
Precision Wide Bandwidth Quad Analog Switches
Features * Single-Supply Operation (+2V to +6V) * Rail-to-Rail Analog Signal Range * Low On-Resistance (6 typ @ 5V)
Description
The PI5A391A/392A/393A are monolithic analog switches designed for low-voltage, single-supply operation. These high-precision devices are ideal for low-distortion audio, video, signal switching and routing applications. The PI5A391A is a quad single-pole single-throw (SPST), normally closed (NC) switch. The PI5A392A has four normally open (NO) switches. The PI5A393A has two NC and two NO switches per package. Each switch conducts current equally well in either direction when on. When off they block voltages up to the power-supply rails. The PI5A391A/392A/393A are fully specified with +5V, and +3.3V supplies. With +5V, they guarantee <12 on-resistance. On-resistance matching between channels is within 2. On-resistance flatness is less than 4 over the full signal range. The PI5A39X family guarantees fast switching speeds (t ON < 20ns). These products are available in the 16-pin narrow-body SOIC, QSOP, and PDIP packages for operation over the industrial (-40oC to +85 oC) temperature range.

The 5A39X can be used to insert various capacitors (C1, C2) and set proper RC times for integration. Resistors R 1 and R2 set initial gain. The RIN resistor X C1 or C2 sets the RC time. The reset switch discharges the hold capacitor through RIN.
