Description
Single-SupplyOperation(+2Vto+6V)
Rail-to-RailAnalogSignalRange
The PI5A391A/392A/393A are monolithic analog switches de-
signed for low-voltage, single-supply operation. These high-preci-
sion devices are ideal for low-distortion audio, video, signal
switching and routing applications.
Low On-Resistance (6ohm typ @ 5V)
MinimizesDistortionandErrorVoltages
R Matching Between Channels, 0.4 ohm typ
ON
On-Resistance Flatness, 2ohm typ
LowChargeInjection. Q=4pCtyp.
The PI5A391A is a quad single-pole single-throw (SPST), nor-
mally closed (NC) switch. The PI5A392A has four normally open
(NO) switches. The PI5A393A has two NC and two NO switches
per package.
Reduces Step errors, clicking, popping noise
High Speed. t , 10ns typ
ON
VeryLowCrosstalk:-72dB@30MHz
Wide-3dBBandwidth: >200MHz
Each switch conducts current equally well in either direction when
on. When off they block voltages up to the power-supply rails.
High-CurrentChannelCapability:>100mA
TTL/CMOSLogicCompatible
The PI5A391A/392A/393A are fully specified with +5V, and
+3.3V supplies. With +5V, they guarantee <12ohm on-resistance.
On-resistance matching between channels is within 2ohm.
On-resistance flatness is less than 4ohm over the full signal range.

1. For conditions shown as Max or Min, use appropriate value specified under Electrical Characteristics for applicable device type.
2. Guaranteed by design.
3. ∆RON = ∆RON max RON min.
4. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified
analog signal range.

The 5A39X can be used to insert various capacitors (C1, C2) and set proper RC times for integration. Resistors R1 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.
