Precision Wide
Bandwidth Quad Analog Switches
Description
Features
• Single-Supply Operation (+2V to +6V)
• Rail-to-Rail Analog Signal Range
• Low On-Resistance (6Ω typ @ 5V)
Minimizes Distortion and Error Voltages
• RON Matching Between Channels, 0.4 Ω typ
• On-Resistance Flatness, 2Ω typ
• Low Charge Injection. Q=4pC typ.
Reduces Step errors, clicking, popping noise
• High Speed. tON, 10ns typ
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.
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.
• Very Low Crosstalk: -72dB @ 30 MHz
• Wide -3dB Bandwidth: >200 MHz
• High-Current Channel Capability: >100mA
• TTL/CMOS Logic Compatible
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 <12Ω on-resistance.
On-resistance matching between channels is within 2Ω. On-resis-
tance flatness is less than 4Ω over the full signal range. The
PI5A39X family guarantees fast switching speeds (tON < 20ns).
• Low Power Consumption (0.5µW typ)
• Pin-compatible with DG3XX, DG4XX, MAX39X
Applications
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.

• Battery-Powered Communication Systems
• Computer Peripherals

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.
