Low-Leakage, Single 8-Channel and Dual 4-Channel, Analog Multiplexer

The DG1208 and DG1209 are low-leakage, low-charge injection, single 8-channel or dual 4-channel multiplexing switch devices. The DG1208 uses three selection inputs A2, A1, and A0 to determine the switching logic; the DG1209 uses two selection inputs A1 and A0. On both devices, an enable (EN) input is used to enable or disable the device.

The low capacitance and low charge injection of the DG1208/DG1209 make them ideal for automatic test equipment systems, data acquisition systems and sample-and- hold systems where low glitch and fast settling time are required.

The DG1208/DG1209 are available in 4mm x 4mm 16-lead TQFN or 16-lead TSSOP packages. The devices are specified for operation over the -40°C to +85°C temperature range.
