Description

FULL DATA SHEET (PDF, 232kB) Download   E-Mail 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 I²C-compatible serial interface. The MAX4563 features a 3-wire SPI™/QSPI™/MICROWIRE™-compatible serial interface. Both parts are available in 16-pin QSOP packages and operate over the commercial and extended temperature ranges.
