MAX4562 Datasheet, PDF (1/16 Pages) Maxim Integrated Products – Serially Controlled, Clickless Audio/Video Switches

19-1461; Rev 0; 4/99
Serially Controlled, Clickless
Audio/Video Switches
General Description
The MAX4562/MAX4563 serial-interface controlled
switches are ideal for multimedia applications. Each
device features 30Ω max on-resistance (R_ON), 5Ω R_ON
match, and 5Ω R_ON 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
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.
