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  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
