The MAX4586/MAX4587 are a series of serially controlled, 4-channel audio/video multiplexers ideal for multimedia applications. They feature 65Ω on-resistance, 4Ω on-resistance matching between channels, and 5Ω on-resistance flatness. Additionally, they feature -83dB off-isolation at 20kHz and -48dB off-isolation at 10MHz, with -84dB crosstalk at 20kHz and -60dB crosstalk at 10MHz. The MAX4586 uses a 2-wire, I2C™-compatible serial interface; the MAX4587 uses a 3-wire, SPI™/QSPI™/ MICROWIRE™-compatible interface. Both devices are available in 10-pin µMAX packages and are specified for the extended -40°C to +85°C temperature range. Applications include cellular phones and accessories, private mobile radios (PMRs), PC multimedia audio/video routing, industrial equipment, set-top boxes, video conferencing, and high-end audio equipment.
The MAX4586 and MAX4587 are serial‑interface, programmable multiplexers that provide a 4‑to‑1 channel switch. The MAX4586 uses a 2‑wire I²C‑compatible interface, while the MAX4587 uses a 3‑wire SPI/QSPI/MICROWIRE‑compatible interface. Both devices operate from a single +2.7 V to +5.5 V supply and are specified for –40 °C to +85 °C.
Key features include low on‑resistance (65 Ω typical), tight on‑resistance matching (4 Ω), and low audio/video off‑isolation and crosstalk values. The devices are offered in a 10‑pin µMAX package and are intended for multimedia, cellular phones, set‑top boxes, video conferencing, and high‑end audio equipment.
