Vishay Siliconix
Precision Quad SPDT Analog Switch
DESCRIPTION FEATURES
The DG333A, DG333AL consist of four independently 22 V supply voltage range
controlled single-pole double-throw analog switches. These
TTL and CMOS compatible logic
monolithic switch is designed to control analog signals
Low on-resistance (25 )
with a high degree of accuracy. The DG333A, DG333AL
On-resistance matched between channels (< 2 )
minimize measurement errors by offering low on-resistance
(25 typ), low leakage (20 pA typ.) and low charge
Flat on-resistance over analog signal range ( < 3 )
injection performance. The DG333AL features micro-power
Low charge injection (1 pC)
operation (< 1 W typ.). This is ideal for battery operated
Low leakage (0.2 nA)
systems. Pin 15 is not connected on the DG333A.
Fast switching (175 ns)
An improved charge injection compensation design
Single-supply operation (5 V to 40 V)
minimizes switching transients. These switches can handle
up to 22 V signals and have an improved continuous
ESD tolerance > 2 kV per 3015.x
current of 30 mA.
Low power (< 1 A) - DG333A, DG333AL
The DG333A, DG333AL is fabricated in Vishay Siliconixs
proprietary HVSG-2 CMOS process, resulting in higher
BENEFITS
speed and lower power consumption. An epitaxial layer
Rail-to-rail analog signal range
prevents latchup. Each switch conducts equally well in both
Simple logic interface
directions when on. When off, they block voltages up to the
power-supply levels. High precision and accuracy
Minimal transients
Low distortion
Reduced power consumption
DUAL-IN-LINE, WIDE-BODY SOIC AND TSSOP
