MAX4562 General Description
The MAX4562/MAX4563 serial-interface controlled switches are ideal for multimedia applications. Each device features 30? max on-resistance (RON), 5? RON
match, and 5? 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 sin- gle-pole/double-throw (SPDT) switches and two normal- ly open single-pole/single-throw (SPST) switches. The 2 MAX4562 features a 2-wire I 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.
