DESCRIPTION
The DG2751 is a compact, low resistance, ultra-low
distortion double pole double throw (DPST) analog switch.
The DG2751 features a flat 0.39 Ω ON resistance over the
analog signal range from (V+) - 5.5 V to V+, supporting
bi-directional negative signal swing. The design brings
superior signal fidelity by eliminating the distortion caused
by double hump switch resistance character of conventional
analog switches.
The DG2751 operates over a voltage range from 3 V to
5.5 V. Because of its low current consumption, it can be
powered directly by a GPIO. When V+ power is off, all switch
pins are of high impedance mode.
Shunt switches are integrated at normally close (NOn)
channels to discharge the AC-coupling capacitance at the
terminals.
The part is controlled by a single bit, S, which can interface
with 1.2 V low voltage I/O. Switch ON/OFF is of
break-before-make (BBM).
The DG2751 is available in ultra-compact 1.2 mm x 1.2 mm,
9-bump WCSP package, and operate over the -40 °C to
+85 °C extended temperature range.
• Low parasitic capacitance
• Low voltage control interface
