General description

ADG787 is a low -voltage CMOS device, which contains two independent single -knife double throws (SPTT) switches. It is designed as a universal modulus converter and can also be used to routing USB 1.1 signal.

This device has a typical 2.5Ω low -conducting resistance, making this part a attractive solution that needs to achieve low distortion applications through switching.

ADG787 has a 10 -ball WLCSP, a 10 -guide LFCSP and a 10 -guide MSOP. These software packages make ADG787 an ideal solution for limited space applications.

When opening, the conduction of each switch in the two directions is the same, and the input signal range extended to the power supply. ADG787 disconnected before switching.

charge injection

During the switch, a measuring method of the fault pulse transmitted from digital input to an analog output.

Non -isolation

Merit not needed signal coupling through a turnover switch.

Response

The frequency response of the connection switch.

Insert losses

The loss caused by the switching resistance resistance.

THD + N

Rising delay

The rise time of the signal is the time measure of the signal from 10%on-level to 90%on-level. The rising time delay is the difference between measuring the rising time at the input terminal and the rising time at the output end.

The drop time of the drop

The decrease time of the signal was to decrease from the time of the signal from 90%ON level to 10%of the ON level. The drop time delay is the difference between the falling time measured at the input terminal and the drop time at the output end.

The ups and downs of the rise and the decrease time is not matched

This is the absolute value between the decrease time and rising time measured at the output end.
