DESCRIPTION

The DG189/190/191 are precision dual single-pole,

double-throw (SPDT) analog switches designed to provide

accurate switching of video and audio signals. This series is

To achieve fast and accurate switch performance, each device

comprises four 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.

ideally suited for applications requiring

on-resistance over the entire analog range.

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

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

on-resistance include audio switching, video switching, and

data acquisition.
