0.37 , Low Capacitance, Dual DPDT / Quad SPDT Analog Switch
DESCRIPTION
The DG2788A, is a four-channel single-pole double-throw
(SPDT) analog switch with two control inputs. It is also
known as a two-channel double-pole double-throw (DPDT)
configuration. The part is designed to operate from 1.8 V to
5.5 V single power rail. All switches conduct equally well in
both directions, offering rail to rail signal witching and can be
used both as multiplexers as well as de-multiplexers.
The DG2788A offers low parasitic capacitance and highly
matched low and flat switch resistance over the full signal
range. It features break-before-make switching and low
control logic threshold. The part supports rail to rail fast
edge pulsing signals and have 0.1 ns/typ. propagation
delay. It is ideal for both analog and digital signal switching
in space constrain applications requiring high performance
and efficient use of board space.
The DG2788A comes in a small miniQFN-16 lead package
of 2.6 mm x 1.8 mm x 0.55 mm.
FEATURES
• 1.8 V to 5.5 V single supply operation

Notes
a. Signals on NC, NO, or COM, or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
b. All leads welded or soldered to PC board.
c. Derate 6.6 mW/°C above 70 °C.
d. Manual soldering with iron is not recommended for leadless components. The miniQFN-16 is a leadless package. The end of the lead
terminal is exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper lip
cannot be guaranteed and is not required to ensure adequate bottom side solder interconnection.

Notes
a. Room = 25 °C, full = as determined by the operating 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. Guarantee by design, not subjected to production test.
e. V

f. Crosstalk measured between channels.
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.
