Vishay DG405 Low-power, high-speed cmos analog switch Datasheet

DG401/403/405
Vishay Siliconix
Low-Power, High-Speed CMOS Analog Switches
DESCRIPTION
FEATURES
The DG401/403/405 monolithic analog switches were
designed to provide precision, high performance switching of
analog signals. Combining low power (0.35 µW, typ) with
high speed (tON: 75 ns, typ), the DG401 series is ideally
suited for portable and battery powered industrial and
military applications.

•
44 V Supply Max Rating
± 15 V Analog Signal Range
On-Resistance - rDS(on): 30 Ω
Low Leakage - ID(on): 40 pA
Fast Switching - tON: 75 ns
Ultra Low Power
Requirements - PD: 0.35 µW
• TTL, CMOS Compatible
• Single Supply Capability
Built on the Vishay Siliconix proprietary high-voltage
silicon-gate process to achieve high voltage rating and
superior switch on/off performance, break-before-make is
guaranteed for the SPDT configurations. An epitaxial layer
prevents latchup.
Pb-free

RoHS*
COMPLIANT
BENEFITS
• Wide Dynamic Range
• Break-Before-Make Switching Action
• Simple Interfacing
Each switch conducts equally well in both directions when
on, and blocks up to 30 V peak-to-peak when off. Onresistance is very flat over the full ± 15 V analog range,
rivaling JFET performance without the inherent dynamic
range limitations.
APPLICATIONS

b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
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.

Dual Slope Integrators:
The DG403 is well suited to configure a selectable slope
integrator. One control signal selects the timing capacitor C1
or C2. Another one selects ein or discharges the capacitor in
preparation for the next integration cycle.

Single-pole double-throw switches are a common element
for switched capacitor networks and filters. The fast
switching times and low leakage of the DG403 allow for
higher clock rates and consequently higher filter operating
frequencies.

APPLICATIONS
Peak Detector:
A3 acting as a comparator provides the logic drive for
operating SW1. The output of A2 is fed back to A3 and
compared to the analog input ein. If ein > eout the output of A3
is high keeping SW1 closed. This allows C1 to charge up to
the analog input voltage. When ein goes below eout A3 goes
negative, turning SW1 off. The system will therefore store the
most positive analog input experienced.
