The MAX4571–MAX4574 serial-interface controlled switches are ideal for multimedia applications. Each device features 35Ω max on-resistance, -90dB audio off-isolation at 20kHz, -60dB video off-isolation at 1.0MHz, and “clickless” mode operation for audio applications.
The MAX4571-MAX4574 are serial-interface controlled switches designed for multimedia applications. The devices feature low on-resistance (35Ω max) and support 'clickless' mode operation to prevent audible pops during switching. They are available in 28-pin QSOP, SSOP, and wide SO packages.
| On-Resistance (Max) | 35Ω |
|---|---|
| Audio Off-Isolation (20kHz) | -90dB |
| Video Off-Isolation (1.0MHz) | -60dB |
| Supply Voltage Range (+5V) | +2.7V to +5.25V |
| Operating Temperature (Commercial) | 0°C to +70°C |
The MAX4571/MAX4572 support a 2-wire, I2C-compatible interface, while the MAX4573/MAX4574 support a 3-wire SPI/QSPI/MICROWIRE-compatible interface.
The MAX4571 contains eleven SPST (Single Pole Single Throw) switches.
The device has a -3dB bandwidth greater than 150 MHz.
