Datasheet Maxim MAX4563 — 数据表

19-1461; Rev 0; 4/99 Serially Controlled, Clickless
Audio/Video Switches
The MAX4562/MAX4563 serial-interface controlled
switches are ideal for multimedia applications. Each
device features 30Ω max on-resistance (RON), 5Ω RON
match, and 5Ω RON flatness. Audio off-isolation and
crosstalk at 20kHz is -85dB, and video off-isolation and
crosstalk at 10MHz is -55dB. Both devices feature
"clickless" mode operation for audio applications.
The MAX4562/MAX4563 contain two normally open single-pole/double-throw (SPDT) switches and two normally open single-pole/single-throw (SPST) switches. The
MAX4562 features a 2-wire I 2 C^TM-compatible serial
interface. The MAX4563 features a 3-wire SPI^TM/QSPI^TM/
MICROWIRE^TM-compatible serial interface. Both parts
are available in 16-pin QSOP packages and operate
over the commercial and extended temperature
ranges. Applications Features
