MAX4562/MAX4563 are serial-interface controlled switches from Maxim Integrated, which are ideal for multimedia applications. They feature 30 ohms maximum on-resistance (RON), 5 ohms RON match, and 5 ohms RON flatness. They can achieve -85dB audio off-isolation and crosstalk at 20kHz, and -55dB video off-isolation and crosstalk at 10MHz.
The MAX4562 and MAX4563 are serial‑interface controlled switches designed for multimedia applications. Each device contains two SPST and two SPDT switches, selectable soft‑mode (clickless) or hard‑mode operation, and supports either a 2‑wire I²C‑compatible (MAX4562) or a 3‑wire SPI/QSPI/MICROWIRE‑compatible (MAX4563) serial interface.
Key features include 30 Ω maximum on‑resistance, audio off‑isolation of –85 dB at 20 kHz, video off‑isolation of –55 dB at 10 MHz, and operation from a single 2.7 V to 5.5 V supply in a 16‑pin QSOP package.
