Vishay DG333A Precision quad spdt analog switch Datasheet

DG333A, DG333AL
Vishay Siliconix
Precision Quad SPDT Analog Switch
DESCRIPTION
FEATURES
The DG333A, DG333AL consist of four independently
controlled single-pole double-throw analog switches. These
monolithic switch is designed to control analog signals with
a high degree of accuracy. The DG333A, DG333AL
minimize measurement errors by offering low on-resistance
(25  typ), low leakage (20 pA typ.) and low charge injection
performance. The DG333AL features micro-power operation
(< 1 µW typ.). This is ideal for battery operated systems. Pin
15 is not connected on the DG333A.

An improved charge injection compensation design
minimizes switching transients. These switches can handle
up to ± 22 V signals and have an improved continuous
current of 30 mA.
The DG333A, DG333AL is fabricated in Vishay Siliconix’s
proprietary HVSG-2 CMOS process, resulting in higher
speed and lower power consumption. An epitaxial layer
prevents latchup. Each switch conducts equally well in both
directions when on. When off, they block voltages up to the
power-supply levels.
± 22 V supply voltage range
TTL and CMOS compatible logic

Fast switching (175 ns)
Single-supply operation (5 V to 40 V)
ESD tolerance > 2 kV per 3015.x
Low power (< 1 µA) - DG333A, DG333AL

Notes:
a. Room = 25 °C, Full = as determined by the operating temperature suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Guaranteed by design, not subject to production test.
e. VIN = input voltage to perform proper function.
f. On-resistance match and flatness are guaranteed only for bipolar supply operation.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

APPLICATIONS
Band-Pass Switched Capacitor Filter
Single-pole double-throw switches are a common element
for switched capacitor networks and filters. The fast
switching times and low leakage of the DG333A, DG333AL
allow for higher clock rates and consequently higher filter
operating frequencies. Figure 8 shows two capacitors being
switched.
The DG333A, DG333AL is capable of switching four
capacitors.
