Detailed Description

The DG1206/DG1207 are single 16-channel or dual 8-channel multiplexing switch devices with low-leakage and low-

charge injection. The ultra-low capacitance and low-charge injection of the DG1206/DG1207 make them ideal for

automatic test equipment systems, data acquisition systems, sample-and-hold systems, and communication systems

where low glitch and fast settling time are required.

The DG1206 is a single 16-channel multiplexer. It switches one of the 16 NO_ inputs to a common output COM, as

determined by the four selection inputs A3, A2, A1, and A0. The DG1207 is a dual 8-channel multiplexer. It switches a

pair of differential NO_ inputs to differential outputs COMA and COMB, as determined by the three selection inputs A2,

A1, and A0. See the Control Logic section for more information.

The DG1206/DG1207 operate rail-to-rail and are fully specified for ±15V bipolar supplies or +12V single supply. The EN

input on DG1206/DG1207 is used to enable or disable the device. When EN is low, all channels are switched off. When

EN is high, each channel conducts bidirectionally according to the selection inputs.

Control Logic

The DG1206 uses four selection inputs A3, A2, A1, and A0 to determine the switching logic.
