DESCRIPTION

The DG186/187/188 are precision single-pole, double-throw

(SPDT) analog switches designed to provide accurate

switching of video and audio signals. This series is ideally

suited for applications requiring a constant on-resistance over

the entire analog range.

on-resistance include audio switching, video switching, and

data acquisition.

To achieve fast and accurate switch performance, each device

comprises two n-channel JFET transistors and a TTL

compatible bipolar driver. The driver is designed to achieve

break-before-make switching action, eliminating the

inadvertent shorting between channels and the crosstalk

which would result. In the on state, each switch conducts

current equally well in either direction. In the off condition, the

switches will block up to 20 V peak-to-peak, with feedthrough

of less than –60 dB at 10 MHz.

The major difference in the devices is the on-resistance

(DG186—10 W, DG187—30 W, DG188—75 W). Reduced

errors are achieved through low leakage current (I_D(on)

< 2 nA). Applications which benefit from the flat JFET
